5 Amazing 3D PRINTED HOUSE Projects

Welcome back to Instagram. Sign in to check out what your friends, family & interests have been capturing & sharing around the world.

I got a idea to make some coral reef rehab parts from Precious Plastic. Background: Current coral reef rehab involves using electrolsys to precipitate out minerals in sea water on to steel frames and then a titanium cathode, all powered by a solar panel on a float. However the titanium mesh is expensive. I see that there is a battery guy, making a conductive HDPE plastic. Basically HDPE infused with carbon and or graphite. It is not chem reactive and will not degenerate in salt water. Titanium is also quite inert but of course the cost for the mesh is quite a lot. So possible a conductive HDPE buoy, with a solar panel attached to it would serve the same use without the big cost?

another thing is that using the precious plastic machines, we can make batteries and super capacitors.

I was thinking. Couldn't you 3D print houses out of reused plastic? I mean the PP machines are basically giant extrusion nozzles. The movement of the device has already been done here: https://www.youtube.com/watch?v=nH-zpnoNLEU and here https://all3dp.com/1/3d-printed-house-homes-buildings-3d-printing-construction/. All you would really have to do is create a nozzle that had a constant flow of relatively clean plastic. (a little oversimplified, but not impossible) If you were in a place with beaches covered in plastic I can imagine people then seeing plastic as a house building material, which would further involve the local community. Maybe even 3D print the workspace that the PP machines are housed in? (edited)

@SemiOptimisticNihilist I know of people having already problems with traditional build materials, laminat, PVC and even concrete. The last thing you wanna do is live in plastic, I think we breath and eat enough of it. But you're right, the PP extruder can be also used as printer but we're all currently lacking resources, infrastructure, research and open source material to conduct the next steps. (edited)

@Catalonia True. I just wanted to get the idea out, ever since I saw PP extrusion videos I imagined it being attached to a giant 3D printer. : P (edited)

Hello, I am looking for a machine manufacturer to mix sand and plastic to make paves and sheets of coating for house and a hydraulic pres machine for molding. The machine name is simple screw extruder machine whasap 005215537757963

@Deleted User : you might have a little more luck in the forum but possibly also making a request in the bazar ! Please remove the request when you're set.

thanks

Hello everyone. I am looking for members who are intrested in SEWING POLYPROPYLENE FABRIC. i work for a manufacturer and they throw away the FIBC (flexible intermediate bulk container) aka super sacks. I have used this material for window shades but i am overwhelmed with surplus. I as the Department head refuse to allow this to continue to be a waste stream. Please help Just to make things clear... I am not advertising, only looking to share resources. These containers are PRESCIOUS and am willing to fold and ship them, any other proceeds would be donated to Dave's Patreon to support PP

@MystroPolymeric Where are you located geographically? (edited)

Has anyone tried to make D&D dice with recycled plastic? The dice have a high weight:sale value, and there are quite a few people who play D&D who go for ethical/luxury items.

2

Never tried it, but it's a very interesting suggestion. My 5 minutes searching told me that dices are either made through resin casted in silicone, or by injecting thermoset plastic. I think it could be adapted to thermoplastic injection. But I wonder which shapes the molds will be for non-cubic dice.

@axez Hey. I live and work in the US. The small state of Rhode Island. I work for a polystyrene manufacturing company and love working with plastics. It breaks my heart to see how much waste we create.

4:05 PM

@Sidequest Co Hey. I thought of a similar idea for oversized die as gifts for D&D lovers. I'm one myself.

@MystroPolymeric a giant d20 always goes down well

It might be a little trickier to make though - perhaps hollow using a warmed mold-turner?

Has anyone tried to make a stemless wine glass or seen a mold that could do it

@Sidequest Co Hey speaking of d20? I found this old project on Dave's website and thought to bring this back. https://davehakkens.nl/projects/memo_blocks/

@MystroPolymeric I`m from Russia. I think shipping to here will be very expensive.

Re: Memo blocks. Even with To-Do and memo note apps on smartphones or watches, I still think people would buy something like that. Maybe in a calendar flip-book style, so memos can be moved forwards, or backwards according to priority. Just for really important reminders or those chores you hate, but must do today. You know what I'm talking about. (Not a question.

Hey humans, just an update on my progress with my heat press, 1. Have been able to constantly make 29.5cm by 25cm by 1cm. 2. Warping aaahhhh! Very close to working this out but frustrating at the moment. 3. I have forgotten most of my woowork skills from school but they are coming back slowly, these are just proof of concept mainly. Any hints or tips let me know. Thanks. Adz.

So been experimenting all today and have finally worked out my warping problem, well a large part of it. Made 2 really good sheets that are smooth. Made a little table with 1 of the sheets, super stoked with it!.

@Zero Plastics Australia Love the sheets you are making! What about using them for worktops and kitchen units for camper van conversions? Lots of people doing it these days. You could target your marketing towards them via facebook pages about DIY van conversion, there are a few and they are very active; people who appreciate recycled products and potentially already looking to spend on such a product. Existing products for this purpose are boring colours and not recycled. They would also be great as a picnic or trail kitchen. https://cdn.shopify.com/s/files/1/1035/4067/products/DSC04010cropped1200-1200_2048x.jpg?v=1568502743

@MystroPolymeric MystroPolymeric Those memo block made me think of Oloids . How about a Precious Plastic Oloid mould collection? Should be a decent profit to be made on these fascinating objects, although they are ultimately without purpose: https://www.youtube.com/watch?v=fRqwYsfiME8 https://www.etsy.com/uk/listing/688301926/oloid-in-cherry-and-oak-size-small?gpla=1&gao=1&&utm_source=google&utm_medium=cpc&utm_campaign=shopping_uk_en_gb_b-art_and_collectibles-other&utm_custom1=2b537524-cf6e-4b7f-ba90-31bb2dc8efd9&utm_content=go_325949088_20231922288_88478128848_pla-116591723129_c__688301926engb&gclid=EAIaIQobChMIkvjo-c_l5QIVA7TtCh24_wAfEAQYAiABEgIqJPD_BwE (edited)

Send one to Makers Muse and I'm sure he would promote it on his channel, he loves Oloids!

@Timberstar that's a great idea mate, I'm in the middle of making more of the tables like the ones above atm but plan of looking into bigger things like this. Atm it takes me 32min to make one 30cm by 25cm by 1cm sheet. As I also work full time it's only now or in the morning that I get time in the shed. I will look into this and thanks again for the heads up.

They silicone moulds are a bit finnikey due to not being able to compress the plastic in them, however, if you take the time to pop bubbles and gently press plastic into voids, you'll come up with some good viable products to sell

10:09 AM

and be careful when you move moulds. if the mould material itself is thin, it can bend and warp if you place it down wonky.

My Instagram messages exploded when I posted my button mould results fresh from the oven.

Hey humans, What's your thoughts on candle holders made from plastic?

That's what I've got so far but just playing around atm. Any hints or tips or ideas that could spark anything would be great. I have this an a simple table that i want to add to market before December if all goes to plan. (edited)

@Zero Plastics Australia : looks nice. might get pretty hot at the candle bottom when leaving unattended. I had glas cups for the candles the other day and set our tend under fire

It was so hot that the glas exploded .. (edited)

1

Oh wow, that doesn't sound good. I tested it till the candles went out, it didn't get get hot which is good but it did spill the was over it when I tried to move it. On a marketing side of things this has 90 bottle lids in it, which is way better than in the ocean or landfill. Still blows my mind what you can do with waste....

Thanks for the inspiration @Ben - Precious Plastic Ciledug :) silicone baking mould :D

1

@Zero Plastics Australia if you're stuck with that sheets now, you could use stainless sheets for the critical part and still use the plastic for structure. working with stainless isn't easy but with a drill press, a cheap tig welder and quite some polishing/grinder tools you could turn this into $$. Of course labor will go up - but the price too if done nice

6:18 PM

You can also design something in Fusion360 (metal sheets) and send it over to the CNC metal braker shop - can be cheap. That way you can already place the mounts, pockets for the plastic so it's all straight forward. You can get it with mirror finish too. Eventually wood & glass gives it a pretty good look too ...

Thank you for the ideas I will have to give these a test soon, with Christmas around the corner now I'm a little broke till the new year. But thanks again I'll show update once I have them.

@Zero Plastics Australia - oh that's tragic. From what I've seen and heard it's kind of impossible to compete with near virgin plastic products - especially if you compete with China. What you could do with the sheets too are puzzle games : https://en.wikipedia.org/wiki/Tangram. I don't know your region but here in the EU it's a classic - especially over Christmas. Possibly you can manage to make the box from plastic too. Not sure sure though how you can archive a nice finish for the edges. There is some little research data in the forum about saws and plastic btw. (edited)

Here is one of the best applications for recycled plastic we've seen so far : https://www.instagram.com/p/B5hVRPYJ6TD/ . It may seem hard to get hand made orthopedic devices into circulation but there often networks and groups who take care about the elderly in this regard - seeking for affordable alternatives.

Wow! Yeah I will have to make one this week. I have the next 2 days off work so I'll try my best to make as many sheets as I can and test this idea with one of them.

@Zero Plastics Australia - yeah, let us know how this goes. I am still puzzled how to make nice edges. Even with the mold approach it seems rather clumsy. If you know somebody with a simple CNC this could look really good (but needs rather flooding). Then as alternative it might be possible to make stamps (like with cookies) and punch the parts out.

Yeah I have been lucky with how mine has turned out with there edges but honestly it's gonna be something that you have to consider when using plastics.

If you didn't yet, please have a look at arselectronica from time to time - there is tons of good material : https://ars.electronica.art/news/en/ | https://www.instagram.com/arselectronica/. They are around since decades and I was lucky to have projects with them from time to time

They do also a stunning event every year in Linz - kinda must go & must have :-). Another great source are the works at TU Delft (Architecture department). Let me find some amazing books back from some of the graduates...

Lots of stuff really.. these were test prints for water jugs ( from a thingiverse model )

@3dSeed what are you using to turn it into filament? doing a similar project

yeah @3dSeed would be great to see your set up / process more detailed!

1

@3dSeed - you said you shredded then grounded the PET - what process did you use to ground it and how fine was it before printing it?

@Kat. Hi Kat, i thought id told you?

11:26 AM

@Kattapa-JU we filter the flakes to dust..

11:28 AM

We are developing a new shredder AND grinder to make the right sized flakes.. More info on Monday :). It will all run on 24V too... Great for batteey powered (sustainable energy powered) festivals.

1

please tag me when the info is released!

11:28 AM

nice job so far!

Email me as we are looking for partners in different countries..

@3dSeed I'd be interested in your shredder/grinder too. Especially, if it works on 24VDC! As you might have noticed in the forum, I'm developing a pellet extruder for my large-scale 3D-printer and I've been looking for a shredder to shred the plastic to small flakes. Ideally the shredder would ba part of the auto feed unit, so you could really make prints out of waste plastic. Let me know! I'm looking as well for global partners later this year when the extruder&printer is ready.

@3dSeed Did not the 3D printer have any harm? Is it custom printer or made of manufactures?

There is a company in Texas that is already using pellet fed large scale 3d printing. Maybe check them out. https://re3d.org/

so, regarding printing PET. Here, finally, the second trial - it was much easier than initially thought :

it's around 150E for the knifes
made for v3 shredders
you just mount 3 knifes on your hexbar
the stationary knife is hold with 2 solid bars tomorrow I run the next tests, it's very possible you can connect this also as extension to your v3 shredder but it actually wants around 600 RPM (may be via belts, right under your existing shredder). However as soon this works as expected, you have the needed flakes size to print it the @3dSeed way. If all goes fine, I add the new machine to the library, docs, etc... but it's really stupid easy to make; 4 hours or so, drill press and a welder and you're fine

(edited)

4

@Deleted User Are those planer knives? If by '150E' you mean 150€ than maybe instead electric hand planer knives could be used - they are readily available and a pair is around 20€

could work, yeah - I got them custom made off from Alibaba. High grade toolsteel, just as PET wants it.

1

hey, regarding PET 3D - print meets PP : I update this with laser files for a new sieve, more videos as well the knife sources over this week in #archived-machines - but more or less - it works alright. There is still lots of space for improving, aligning mobile knifes to the stationary one. A slight twist angle seems perfect - hence the name 'grinder' I guess.. I tested it on the lathe since I had no motor. The standard 1500RPM will be fine too, otherwise 600 is optimal. Next thing is then a larger printers though - we're not short of PET

@Deleted User great! One note though - from my experience with similar knives configuration - they are more dangerous in operation since they don't pull the shredded products inside the shredder but rather kick it

2:03 PM

That results in the plastic bottles/items being kicked out of the hopper

2:04 PM

So the lid and/or some'pusher' is necessary

hence a good door - yeah - the twist angle seems to determine it's 'chopping' or 'grinding', making the mount holes big enough gives enough space for alignment. but yeah, it's loud and messy - the idea is to mount this right under the v3 shredder since it wants 5-8 mm flakes. but hey, let's continue this when the source files are ready, preferably in the #archived-machines channel - at the end of this week.

Hi everyone, wich type of plastic do you recommend me to make small high quality products with the injection machine??

@GeorgeFields HDPE is our favorite

hey, regarding PET 3D - print meets PP :

@Deleted User PET is very brittle unless it’s polymers are anisentropic (running in a single direction) blow molding does this for bottles but you would need to add glycol in very controlled mix to make PETG for 3D printing which would probably require very expensive specialized mixing machine. PET has this highest “street value” in South Africa so we can leave that to the informal waste collectors. Polypropylene, HDPE and ABS are all good polymers to work with in PP machines (edited)

2

@Deleted User what is the capacity of this machine?

right now it's at a KG in 10 minutes -I am doing last minute changes,optimizations, documentation today. I guess I can get it to 50 - 70 KG the hour - it's pretty cheap and simple to do

(edited)

12:03 PM

docs & videos go out tomorrow - it's rather a side project and still needs some updates though

@Deleted User this same type of design is more popular here in India, and is much more effective. Here is an example- https://youtu.be/tG2yP9IYRr0

Ansari Machines

24 Inch Scrap Grinder | Ansari Machines

nice, yeah the one here is rather to grind industrial flakes of 5-10 mm down to 0.7 - 1mm particles - ready to print - there are still open challenges : washing & drying ..

@Deleted User this might be useful https://youtu.be/3xWvHz9JjjU

@sharma.sagar94 : I just hopped through all the other videos - I am BLOWN away, seriously - lot's a of good takeaways; really nice - thanks a lot - looks like I have to spent some weeks ON the drawing board. Their grinder is way more effective & efficient than the little one here to print stuff right afterwards. I think I copy the double 4 stationary knife design. (edited)

@Deleted User yeah. I've been saying this on the forum

8:53 PM

@sharma.sagar94 can I DM, I've got some other stuff to show

@sharma.sagar94 : sure, go ahead.

@Deleted User add me as friend only then dm will go through

Friendssss will the new bazar have the ability to show prices in local currencies? Cause that would be amazzinggggg

Bazar questions should actually go in the #deleted-channel channel. And only the developers can answer your question.

Been having a big problem lately with my plastic sticking to the mold. What do you all use to prevent this?

#deleted-channel

@Angus17 silicone oil

what do you guy do for cleaning your plastic, prior to shredding, or post shredding?

Post shredding You can deliver the plastics directory to the water tank. There also you can sort automaticly some kind of plastics

i suppose you would need a large water tank if you were washing a quantity of plastic containers.

3:17 PM

I am working on a machine to handle this process. but curious what others are doing.

Depends info your quantity

3:18 PM

Mine, i use 3 tanks. 1x1x0.8meter

Hey guys! We are Sophie and Alex from Melbourne (Australia) - we have been experimenting with plastics for some time and helping set up a studio in Melbourne (Proto Hub) so we are using a shredder and compression oven

We have got some cool results but we have had trouble with our triangular planter pot mould...so we are redesigning! Would anyone be up for having a look at the mould design? All the best! Looking forward to some inspiring conversations here on Discord!

@🤙v4-team @Colourful Collective who would be the best person or persons to talk to about mould design or should this be another channel? (edited)

This should probably go in #archived-machines. Maybe try your nearest machine shop on the map. Or maybe get a quote from a machinist that can make a prototype and ship it to you? Basics tutorial for designing: https://community.preciousplastic.com/how-to/design-an-injection-mould And active pings require the emoji in the role or username. Like: [at]v4-team .

10:29 PM

@Colourful Collective I am in QLD but happy to have a look at this. Why don't you post some pics of the failed parts, and the mold your currently using.

OOh that would be amazing @Sunshine Coast Maker Space !

So our first mould that we made was too big and there were too many sharp angles, and it was really hard to get anything out of it!! Plus it was too big for our oven

I mean we got it in there, but didn't have much space to work with. Here are some pics...

7:36 AM

7:38 AM

7:41 AM

so here are the four parts (the planter pot mould and it's saucer)

7:41 AM

this is how happy I was when we finally got it out!

7:42 AM

7:44 AM

We've decided to rebuild, as the mould is really problematic. We are concerned that the next mould wont work either! Hence why we are looking for lots of experienced opinions/tips/advice/help! So here are the designs for the next one. We are working with the oven, and have been making coasters and a few other things from found objects (like lids and bowls and trays) without using any compression and have been having some cool results. But we are really keen to move forward with this planter pot!!

1

7:45 AM

what didn't work exactly (edited)

7:45 AM

Any thoughts much appreciated!

@Colourful Collective for a deep draw mold like that, maybe split it so the outer is like a clam shell. That will make it much easier to demold. Or add ejection holes on the bottom. Or jacking screws to jack the inner out of the part from the flange.

1

8:14 AM

Stack from today's tests

@Colourful Collective you could add triangular 'ejector plate' at the bottom welded to a short rod sticking down through the hole in the actual bottom mould. After cooling down you hit the rod sticking out and it should push the pot out of the mould. (edited)

1:38 PM

@Colourful Collective also, did you use any mould release spray?

@Colourful Collective https://www.instagram.com/p/BuCQif8HxDZ/?igshid=vx8uy71fh2zr

Oooh thanks for the ideas @Arseniy (PL) and @lechatblanc ! We did use some mould release spray, I will hunt for the name to tell you.

PP Coin for Polypropylen by Manuel M on Precious Plastic Bazar

@Thomas Peterberns | Johannplasto the link points to someone also requesting the coins ^^ I think they were sold out a while ago, maybe someone from @🤙v4-team can tell us if there is a plan to make some more ?

Oh, ok, just rememered that i saw this on the bazar

tell us if there is a plan to make some more ? Better yet: A How To on the site for making the coins. (edited)

@Frederik C (ZA) there's actually a how to on making custom stamps with copper wire but the coins look way, way better

1

One option is to hand engrave your own logos and recycle-marks. I don't think there is a plan to make/order more jet @Joseph ? Its kind of hard to make them I assume, you need a biiig press for it and probably order 1000+. Also we found that the last set of coins was a bit tricky to work with.

There is a way to do it, but you need a CNC machine, and I search but really difficult to found something in my price

Perfect opportunity for regional distribution of difficult-to-make items, on the bazar or otherwise.

yeah - I tried making a coin on the CNC - it's really difficult to mill stuff that small - I gave up after breaking a dozen of end mills, it would take around 4 -6 hours to make one coin just. (edited)

@Deleted User oh damn, okay thanks. I will look for another solution

i could do it on the CNC as well, but i doubt people would like to spend 12€ + shipping? @Elora

Surely a high-quality mould should be made so the copper can be cast? A set of moulds goes to each region, each region casts a set of coins for each workspace... that kind of thing. It's the mould that is difficult. DIY copper casting is doable, with practice. It's only about 7 - 8 coins per workspace. Also, does it have to be copper? Aluminium casting is easier. (edited)

@Frederik C (ZA) never thought about aluminium, and actually it’s a good thought, I have a DIY fondery may be I can make molds (edited)

1

9:38 AM

@Fritz @easymoulds why not actually, but first I will try to do it with my fondery, and thanks

We made our stamp from a person who makes stamp for leather products and an arbour press to make an imprint on our products. Works great for pp and hdpe products.

Another idea - ask you local signmaker workshop to engrave one for you! They have high speed spindles, so they might be able to do it much faster/cheaper

1

@Fritz @easymoulds yes i want to do that but I’m literally lost in south of France and I can’t found a local sign maker workshop! But I’m going to the « town » in few weeks I will search! Thanks!

This is partly what the Maker movement is about. Bringing back forgotten skills.

Us "sophisticated" modern people, struggle to do some of the things that people could do before electrical machines existed. However, previously, it was passed from master craftsmen to apprentices only. That's where, this time round, the web and open-source changes the game.

very nice @Pradyumna Rao :)

1

indeed ! @Pradyumna Rao you just press the stamp on cold plastic ? (edited)

12:34 PM

would you consider documenting this technique in a how to ? I'm sure lots of people will be interested !

@John yes I press the stamp on cold plastics. I will definitely document it and put it up. This works great for surfaces that are smooth. If there is too much texture like the beams we make it doesn't work great.

What are the lamp heads made of?

9:35 AM

@Frederik C (ZA) Papier-mâché from a homeless magazine called Σχεδία / Schedia

I didn't know that can be heat-resistant.

it use led lights anyway, so little heat. They are on all day, in a cafe they have and in the shop where they sell them (I meant Schedia, which is the client)

Off-grid table lamps with rechargeable battery / power bank in the base sounds good to me. We are having daily power-cuts in South Africa.

(edited)

Funny you mentioned that, because I am experimenting with a camping version, that uses only plastic for everything (including screws) and a mechanically powered flashlight

1

@Plastikourgeio Do you have to test the lamps before you can sell it? Or do you use finished and tested lamp kits (includes cable, plug & socket)?

@Thomas Peterberns | Johannplasto finished product. The electronics are very straight forward, although we do a basic function test: switch power test, high potential/hipot test, power cord anchorage test, power cord length test. The client provide us the shades and we create the mold base with their indications (usb charger, switch on the base, round base, etc) , so we also test the shades for heating tolerance level, just in case they use something else than led

Hi guys! I'm new. Fell in love with PP from the first video and I'm now helping to setup a community here in Lithuania. One of the questions is the business side. Has anybody have any links/material/experience/numbers/anything to share about how much this can be profitable? Is it possible/easy to break even? Any example or real world cases would be awesome! I believe we got sorting, item design, machines and ideology covered at least on some level, but the business side is struggling - any help would be very much appreciated!

Hi. I would like to set up a dome or two. Is there anyboy injecting the 6-way and 5 -way joineries? I can't find these parts on the Bazar. I would be interested in 40 and 12 pcs.

I used my extrusion machine to inject a 15cm x 15cm x 15cm mould mixed with gravel. the rotating mechanism for the mould failed so the rocks stayed at the bottom. however, there was good penetration of the plastic into the settled gravel. this is a project for some civil engineering students.

2

2:29 AM

This was created using HDPE flakes and hot gravel. Plastic and gravel were put in layers and heated in oven until plastic melted down each time. It took a while but the results look quite interesting. later they plan on cutting this in half to see what it looks like inside. Also a project for civil engineering students. I did notice that there's some cracking of the plastic in areas close to gravel likely because the HDPE shrinks and the gravel does not. But i'll be interested to see what their results are for how strong it is.

Just a simple square mould

Guys, I have a business related question - do you sell your products, how do you distribute/promote them, what sells wells in your experience and has anybody actually manage to take off and have a sustainable business with PP machines and the whole model? I'm based in Lithuania and we're working on starting a community here and would be good to know such things. Thank you!

Test molding some compression molded grain elevator buckets. Plastic is a mix of coke and gatoraide caps. Extruded and pressed. Still working on temperature settings and liquid cooling the mold today we will try.

@Zero Plastics Australia Those are nice. What plastics and sources are you using for these?

@MAALK didnt think they would sell to be honest but after the feed back I've been having maybe I should. @Arson These are HDPE, the white is the mix I get from a recycling company near me and then I sort out the lids I collect into these 3 colours and then mix with the white.

hey, regarding PET 3D - print meets PP : I update this with laser files for a new sieve, more videos as well the knife sources over this week in #archived-machines - but more or less - it works alright. There is still lots of space for improving, aligning mobile knifes to the stationary one. A slight twist angle seems perfect - hence the name 'grinder' I guess.. I tested it on the lathe since I had no motor. The standard 1500RPM will be fine too, otherwise 600 is optimal. Next thing is then a larger printers though - we're not short of PET

@Deleted User Any updates on this?

@sharma.sagar94 : well, the small printer is ready, also the grinder. the big printer is in development , we teamed up with @Timberstar but this one will last quite a while. we're posting on the old forum and here when the docs are complete, will ping you myself

@sharma.sagar94 : project updated : https://github.com/plastic-hub/products/tree/master/products/idefix , includes also the links to the PET print head

@Getthip Do you have a picture of your mould of the Water color palette? Thanks!

I extruded at higher temps, hoping to solve some quality issues. It just bubbled instead. Better shapes worse finish. I duplicated the plastic hub shredder using wood plane blades. Yea it works... Nay it shreds bottles. It absolutely hates plastic bags. bent a blade on a chap plastic bag. Prob just use to reprocess granules into finer sizes.

7:40 AM

@sharma.sagar94 , some important details are missing (alibaba contact), lets see what master @Butte (PP Philippines)´s grinder is capable of

@Deleted User The small grinder based on yours was a fail. It can only reprocess flake. I used 3.5 inch wood plane blades. Cheap china price was 2 usd each, good milwaukee brand is around 6usd each. Plastic bag no luck, plastic bottle it just flopped around. Much bigger shredder is still awaiting parts back from laser. Many unknowns on that one. Bought a new MIG welder specifically for this build and ahead of pur planned schedule because NCOV virus is making things rapidly unavailable here. Bearings gettingharder to find. I can find SKF brand at 3x the cost of the Japanese I was sourcing and Chinese stuff is almost gone. Placed orders for temp controllers online and selector switches. No luck, no one is shipping. No heater bands too.

@Arson Oh nice, how did you made it?

I used a CNC mill. I designed a 3D printed jig for holding the pieces while they are machined. I hope to sell them and use the profit to build out the rest of the workshop. My shredder is supposed to be shipped on Thursday.

@Arson Any chance that you can make and sell a casting mould for the coins? Also, can you make custom logos for other workspaces?

@Frederik C (ZA) Possibly. What sizes are we talking?

10:43 AM

I can make custom logos if someone has the drawing files

10:43 AM

Just started with stamps so people could heat them up and mark their products

What sizes are we talking? I'm not sure.

Small enough to be aesthetically pleasing, but big enough to read, I guess. I suppose I'd have to print one on paper and see how it looks. But basically the size of the smallest money coins. Or smaller.

I can machine aluminum and brass. But I wouldn't be able to do something harder than that.

10:54 AM

The one above is 1 inch width. I got some 0.5 inch coming in to try.

Well, maybe that will work. I was just thinking that spending a bit more on moulds, means that the standard coins can be reproduced by less-equipped workspaces, on demand. A custom logo coin, only needs to made once, of course.

Yep. I have the stuff to build my large CNC. 2.2kW water cooled spindle and all. Just need the spacce and time to build it

10:57 AM

It should cut whatever I want.

10:59 AM

I'd definitely be willing to give it a go

Luckily, it's not a huge package to ship. So, one workshop can pretty much supply most of the World.

Yeah. I'm hoping to fill the niche so I can get reinvest into buying the other plastic machines

@PlasticAtBay_Julien_NScotland what do you make from the beams

@Sieara We are planning to do some small furnitures like stools, I also use the beams to build up a little porch in front of the Lab but that's when we will have less storms and blizzard. At the moment working on acoustic treatment so that the workshop is less noisy... Basically you can do what you want, it is really versatile and sturdy. Although it should not be used for structural support in theory as it has near 0 elasticity.

That's still really cool.

Hey guys I've recently started having my sheets "peel" for lack of a better word. It's like the plastic starts to layer but doesn't set. I haven't changed anything in my process and are using the small type of plastic. HDPE. Any tips of fixing this?

Contaminated feedstock maybe?

1

All the same stock, I just checked my molds however and notice a little bit of rust appearing on them, maybe that is the reason.

Maybe you need to heat up higher to be sure the mixing of melted polymer is better

Yeah that's the thing I haven't change the stock or the heat/settings at all. The only difference that I've just notice is this rust appearing on my molds. I'll sand them back and see if that helps.

1

@Zero Plastics Australia rust would transfer heat differently than the plain metal. It could be that you need a higher temperature and/or longer time once you get the rust forming.

What are the moulds made of?

Aluminum sheet metal, 5mm thick.

Hi, I'm trying to put my products in the new bazaar, but there's no option to do this, only order. Anyone has the same problem or solution?

Hi guys do you have Huawei phone cases on sale??

1:10 PM

I will love to have one

@Zero Plastics Australia aluminum oxide and rust are both relatively good insulators compared to their base metals. If you're developing them through operation rather than environmental exposure, you may be having an issue with moisture content in your feedstock. If you're in an area with high humidity, the plates may be developing condensation when cool, so you'll want to keep them dry, and limit heat/cool cycles if you can.

@Trukku (Ohio, USA) thank you so much for this.

Hi everyone! how do you recommend washing the Plastic? In it's original form as caps and bottles or in flakes?

@GeorgeFields I think the question would be better asked in #archived-plastic , but I think that usually it's both, especially if the bottles are really dirty/were filled with something that just don't "flow out.". (Something thick or greasy) The first wash wouldn't be really precise/careful, but just to remove most of what was inside. (edited)

Sorry, got a bit excited when I took this photo. I've probably been playing with silicone moulds a bit more than I should but it's hard not to when you get good results without a bubbly mess.

How did you form the silicon mould? In wood?

Actually a friend bought them over but was unsuccessful in using them so I gave it a shot. The moulds appear to be of a 3d printed shape due to some details I see. I'm not sure how they were formed but it's just a guess.

@Lazy_Turtle I think it´s a thermoset, so you can´t recycle it...

Yeah that's the thing I haven't change the stock or the heat/settings at all. The only difference that I've just notice is this rust appearing on my molds. I'll sand them back and see if that helps.

@Zero Plastics Australia Hey Adzie your sheet press might not be functioning as well as when you got it adjust up 5-10degrees to see if this compensates for the delamination. or the spring on the press is not as strong and therefore not giving you as much pressure as before.

@sharma.sagar94 3 1/2 minutes

9:24 AM

The only difference that I've just notice is this rust appearing on my molds. I'll sand them back and see if that helps.

@Zero Plastics Australia You need a work surface that doesn't rust or else you will always have this problem. It can be stainless steel, aluminum, brass, copper... Just be aware if you use a soft metal you need to be extra careful to not damage the surface as it will be imbedded in whatever you're making.

@protohub @Ben - Precious Plastic Ciledug yeah after changing this to a thicker sheet and sanding it back it now works a treat. I was thinking of selling kits of my machine so others can make sheets like mine now as I've almost got it down to a T.

Question: I have to make a HOLLOW product looking like this yellow shape. How do I build the mold so I can take it out again? Ideally, I want to freehand apply it on, soI can tale off afterward, to obtain a similar texture like this vase in one of the videos. (The freehand technique i am referring to is similar to the one used to what is used in Jaden table video: https://youtu.be/VlsAw1LlnCs?t=83) my own suggestion: To mold the thing divided into two shapes, and put them together later. (That being the round top part and the wide pipe) I was thinking to mold the round top over a bowl (anyone with experience with HDPE letting go of ceramics again?) But the large diameter pipe I have no idea what to mold over? I was thinking to make something in wood, but now sure how safe it is, and how to make it release from the mold again. NB: measurements are estimates, there is no need to me to be exact. (edited)

Jaden - Plastic Table

Probably a crazy concept idea but a hollow object could potentially be made by having the mold moving with high rpm to get the plastic bits on the outside only

@Natu 🇺🇸 [Ohio] it doesnt need to be high rpm, rotation moulding is a thing. The plastic has to be ground very fine though. Its how most large thin-walled plastic objects are made- canoes, play equipment etc

@Timberstar I think you and @Natu 🇺🇸 [Ohio] misunderstood how i want to apply the plastic. I am melting it and then applying it with my hands and a spatular like tool. (like in the video link) But thank you for the recommendations

@Si Mo Ne that vase was a unique piece. we only made one. And that was made with a paper mould and extruder on top of it. And later we could rip out the mould

@davehakkens thank you for answering! It looks nothing like an extruder pattern, so would never have guessed! - interesting with the paper mould, is there a tutorial or another example anywhere?

nha we didn't really like the technique. A bit wasteful with the mould so we didn't share it

@davehakkens that makes sense. thank you for your help

@punksout Well there are other major things which turned not so well for us like with machinery... We have a shop and we can receive 100+ people a day during the season. I am personally totally against Amazon so there is no chance I will step in that direction. The shop will not run this year except if there is a miracle regarding the epidemic (projection till September here). We missed last season because of delays and the fact we had to rebuild and modify our machines. We might go towards Etsy but I would not be surprised that all shipping end soon here. I had to send my ranger home yesterday so no more removal of pollution. So except working on building up a stock and testing new ideas, there is not much choice for us at the moment. @Uplifted In general we upcycle things which are not recyclable like the fragments of fishing buoys which are thermoset (we make soap dishes, lamps, toys for the horses etc), some objects which are massive like fish farm feeder pipes (We make furnitures, horse shelters) or things that could be a waste of energy like 35m of nice rope (we make mats). In general, we try to waste the least energy possible, it is up to you to repurpose objects. The thing is that we work with pollution, we don't know what the ocean will spit out, we adapt. Sometimes you leave stuff in a corner for a while because you don't feel like sending it to landfill. Then one day, you find a use of it. It involves quite some hoarding but with a bit of organisation, it allows doing some cool stuff.

Dave Hakkens

Melting temperature tests - Dave Hakkens

There are different types of plastic and each plastic has its own melting temperature. You can easily find this online. However there is a big difference between the melting range between - Dave Hakkens

5:05 PM

"Depends a little bit what kind of technique/machine you are using. The metling temperature is around 260 degrees. However compared to others types of plastic with PET this is very crucial. Couple of degrees above or below make it unnamable –is that a word? You got a picture of your machine?"

Dave or his friends explains that "PET is a very strong plastic that can be easily recognised for its transparent look - all water and soda bottles are made from PET as well as some jars, combs, bags, tote bags, carpets and ropes, and is recycled more commonly. Recently, PET has been recycled into yarns and made into clothes.

There is a problem in extruder . it is not able to extrude material .i think this is because there is 3-4 mm gap in between screw and extrusion barrel and screw is slightly eccentric(i.e it is not exactly in centre of barrel) .is anything else because of which this might be happening?please give your suggestion .

3-4 mm gap will ruin your barrel

should be more around 0.5 mm difference only

if it's 25 exactly, it might scratch the barrel. barrels come usually up 0.1mm undersized

Thanks for references .Will get one after this lockdown is over.

I use a 25mm wood auger in a 25mm ID extruded tube ad it fits perfect. No undersize whatever. What i did though is smoothen the edges of the drill with a file.

@sonik lucky you - here it´s consistently 0.1 - 0.15 undersized, for all the 40 meters (in different sizes) I bought over the last 12 months. you have a good file, the wood augers i had were extreme hard, even the angle grinder didn´t take off much (edited)

So i made a skateboard out of a sheet i had laying around the other day and after trying to land a kick flip snapped it in half haha. The best thing about this is i just recooked the sheet and can make it again. Love working with plastics.

@Zero Plastics Australia super cool buddy

Hello we setting up a small recycling workshop at a primary school here in Singapore. I am looking for a mould design for a marble run. So the youngest kids can play with the items we make. Does anyone happen to have this.

3

@joost : that´s excellent idea and a perfect example where PP can shine

You can do this with the traditional molding process (model and CNC mill) but I´d give it a try on the extruder with custom beam molds.

10:21 AM

the custom beam molds are quite easy to make, you take a tube, cut out a slot and weld a cylinder in place

We have an injection press and access to a CNC milling machine But was wondering if someone has the design in 3D already.

no, but this is easy to make in Fusion360, take some of the tutorials on youtube, you could do this in less than a day, in another day you can make the CAM operations as well. Also check "skillshare" for courses. (edited)

10:25 AM

it´s mostly beams

It probably is not that hard, but copying a mould which has already been tested is even easier !

from what i see this shapes don't need critical draft angles or such; it would shrink and fall off in both cases, injection molding, beam molding.

@joost : there's also a popular thread in the forum : https://davehakkens.nl/community/forums/topic/portable-desktop-injection-machine/

@joost if you look a little up this post i recently made a marble run from sheets. My son loves it and it was really easy to make.

ya know, i think it would help a lot if we can get numbers for the actual force and speed needed on the plunger.. if the linear actuator are too weak we could calculate what motors would be needed to make a rack or ballscrew version with gearing

Hi, Any information regarding basket potential production ? I understand its injection based on HDPE ? From what I've checked. interested by possible processes than machines. Thanks !

@Deleted User A basket is quite a large object to inject in one piece.... but people are making baskets with the extruder

Thanks @Deleted User for the link to preciousplasticukraine https://www.instagram.com/p/B-_paR5nwqj/ So interesting to see their prgress from the first simple machines from wood to now

yea, mind boggling

I always find it ironic how humans chop down a birds home to make a birds home

So why not use plastic waste instead?

This little bird feeder took just over 750 plastic bottle caps to make, cleaning up our planet

️ instead of destroying it for our gain and to tick some kinda feel good box. ✅

@Zero Plastics Australia I would love to see a how-to on that

(If you have time)

Unfortunately as i was making this with my 2.5 year old and wife we were having to much fun building this to take photos, but i do have a how to in the works for how i make my sheets and im trying to make "kits" that people can buy in order to start doing what i do, as the sheet machine from v4 is a little costly and hard to make if you are just starting off.

Lamps from recycled PP i made, let me know what you think! Question: is it possible to extrude beams with a profile of 20x20mm or even smaller? I have seen larger profiles but not thin ones. This could mean the lamps can be completely made of plastic.

@timisalabimi yes I do most of my beams as 20x20x500 easy and fast to make

@Lazy_Turtle had not thought about just glueing the parts together without frame, might experiment with that!

@timisalabimi so beautiful. how’d you make these colors. My products’re always black or gray. Thanks

Pls hepl me. My product’s black or gray.

@Ken Tran Which color was the plastic you originally used ? If you want colors, you need to used colored plastic. If you did use colored plastic, maybe you're overheating it and it's starting to burn/discolor? It also depends of the type of plastic, which one do you used? (edited)

@Ley Klussyn how much temperarure?

@Ken Tran It depends on the plastic type, your process/machine, and time. You could start by checking out the academy if you didn't : https://community.preciousplastic.com/academy/plastic/basics By "color plastic", what I mean is that if you want to make a red object out of HDPE, you should use red HDPE and not black HDPE. But there isn't really a "kind" of colored plastic, it's all about the type of plastic. (edited)

@Memosogtf what size of beam? what's your extruder setup?

Hello everyone, I´m very new to the community. Just wanted to check if who is based in the south of México? I only see fellow mexicans in the north and in México City. I´m in Tulum, Q Roo.

this is the starter kit shredder. does anybody have the blueprints to this particular machine. I have searched the downloaded files but the blueprints for the starter-kit shredder where no where to be found. in the starter kit file the shredder pro was in that category. i don't know why. if one of you have the blueprint that will be very helpful. send me an email at 12flachner@gmail.com. Thank you

I´m playing with the idea of making products for gardening. Love plants and loving the idea of recycled plastic. It´s a great community Precious Plastic, LOVE IT. Regards from Tulum !

@Carolina i already have the prints, someone helped me

I teach at a school in The Hague. Next year we will be opening a new workshop, specially aimed at engineering and more specifically recycling and sustainability aimed at children aged 10 to 16. Because our workshop is near the harbour we are looking at using waste from there. We are working on a series of tasks which we will be developing the coming period. For these tasks we are looking into buying some machines like the shredder/extruder/injection/compression and sheetpress. So we would like to get in touch with someone who could help us out. Could someone direct me to someone who could help? Thanks a lot in advance.

3:12 PM

One question I have straight away concerning a permit. Will the machine need ventilation in any way?

Made these from my sheets, but what should i make next? Any ideas?

@Zero Plastics Australia The top-right one looks very cool. It would be great to develop customization like bricks. Maybe making a hole in a sheet and inserting short beams? The other ones look very cool too.

11:15 AM

Would be great to see a how to on that if you have time for online stuff.

1

@Zero Plastics Australia that s cool. hey quick question. how thin of a sheet can you make and is it flexible?

@Zero Plastics Australia , If I'd have the time, I'd try copying kitchen appliances (gears, mills,...) , educational apparatuses (gears as well, mechanics, math). Needs of course a mini CNC (a little stronger); not sure about the consensus - but it seems it needs to be water flooded, at least according to the books. (edited)

2:18 PM

well, more games would great though too

@Beginner's Tech haven't really tested it as i was trying to make max size, i have made 0.4mm and it was flexible bit also wrapped a bit

4:26 PM

@Deleted User yeah great idea, i plan on getting these cut into other shapes so I'll test out gears

@Zero Plastics Australia I would love to try to use sheets for Vacuum forming.

How thick would the sheets need to be for that?

I think they more so need to be thin?

11:43 PM

~1-3mm?

11:44 PM

There are two general thermoforming process categories. Sheet thickness less than 1.5 mm (0.060 inches) is usually delivered to the thermoforming machine from rolls or from a sheet extruder. Thin-gauge roll-fed or inline extruded thermoforming applications are dominated by rigid or semi-rigid disposable packaging. Sheet thicknesses greater than 3 mm (0.120 inches) are usually delivered to the forming machine by hand or an auto-feed method already cut to final dimensions. Heavy, or thick-gauge, cut sheet thermoforming applications are primarily used as permanent structural components. There is a small but growing medium-gauge market that forms sheet 1.5 mm to 3 mm in thickness.

11:44 PM

grabbed that from wikipedia

11:44 PM

https://en.wikipedia.org/wiki/Thermoforming

Thermoforming

Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated ...

@Memosogtf I don't know if you had your answers about extrusion time for beams but I can help! I extrude different size and shape of beams with the normal version of extrusion It takes 45min to extrude 1.30m Rectangle beam (3x6cm Rectangle) & it's 2kg of plastic 20 min to extrude Rectangle the same but 70cm long - 1kg of plastic 10min for round (3cm diam.) , 30 cm long Hope it can help! Also I find it hard to extrude long ones, especially if the mold is cold, but where I am (Cambodia) I can just let it under the sun for few minutes and it's good..

11

@Alix i was just reading your comments about extrusion (i'm getting started with extrusion myself), and a question came to mind ... do you use normal metal beam molds (as shown in PP videos)?

@Memosogtf so your using an wooddrill as a feed screw ?

@gustavomaske yes it's standard metal but for the longer recabtgle one I get a thicker and better quality one and I can see the difference..

beach style chairs may be a great product!

@Alix cool, by difference i suppose you mean the finishing right ?

Yes but mostly for the extrusion process. If you use too thick metal, it can bump when you inject plastic in it, make like a big belly in the middle and then it's tricky to un mold...

nice stuff! i've seen similar 3d prints be VERY popular

@Eric Lotze I was going to take photos of the process but got distracted, using my sheet press machine I make sheets 30cm x 25cm x 1cm then cut it using a table saw and hot glue gun to join it.

1:50 PM

that's fine lol

seems just like sheet work

1:50 PM

did you use screws/ or woodwork joints?

100% like using chipboard

1:51 PM

Just a hot glue gun

1:53 PM

I've tried plastic welding but not that good at it and I found a hot glue gun works really well for strength.

I am getting a guy trying to do joinery with our beams. I think it should work. I am awaiting for his feedback

with a CNC Router, or some sort of woodworking equipment?

5:45 PM

also have we plotted molds with this integrated?

5:46 PM

ie a "2x4" type thing lets say a meter long with joinery on each end?

@Thomas Peterberns | Johannplasto I don’t understand

@1plasticlife Looks doable. But maybe give us more details. Minimum thickness, volume, which injection machine, plastic type (s), ... The arrangement of the mold nests already makes sense to me.

Is there someone here selling row beams from extruder V4? (Possibly shipping from europe). I would to make some test before building the machine

thanks

Hello there ! I had a project in mind for a long time but haven’t got around to doing it. I contacted precious plastic in Lancaster but they don’t work with the type of plastic I have. I had a transplant many years ago and I have been keeping my pill packaging for a few years now. It is PVC and foil (impossible to separate both). I know that burning it releases chemicals but the idea is to shred them and then glue them together in a mold of some kind to create something (sheets/coasters...) anybody in the UK or elsewhere willing to help? I have a whole community of transplant recipients willing to recycle their packaging !

Put this little fella together today, happy with how it turned out. (edited)

Can you please tell me size of barrel for injection molding machine.. Like length and diameter of barrel... Please

wondering if anyone has been messing with this stuff?

@Butte (PP Philippines) I have 2 potters near our workshop and their small kilns would have these. By design I think they would be interesting for eating up air not in contact with metal. We are having discustion on using rocket fuel concepts to heat up some machines to be energy efficient. If you use these I would recommend to actually insulate with fire bricks. It will probably work better.

Hi PP community! I'd like to introduce you our upcoming large-scale 3D-printer model which will be able to print with shredded plastic. It's internally refered as Bloft MK2. We've been developing a large-scale printer since 2018 based on the Hangprinter concept, and today, after a long design stage, we're finally starting with building the first prototype of the MK2. The printer specs are as followed: 4.5 m tall, footprint 4 m in dia Print volume approx. 2.7 m3 with a print surface of 1 m. Pellet extruder with approx. 1.5 kg/h output. 600 W combined heating power, 3 heating zones. The printer will be controlled by a Duet3 board, with ODrive boards driving BLDC-motors acting as servo motors for the motion. The printer has an unique motion system based on steel wires and an extendable frame size. That means whether you need it rather small or really huge, the frame and motion system will adapt to your needs, with only small extra costs. Mainly for the extra long steel wires. We will pilot this printer in the fall as part of the Baltic Sea Challenge quick experiments by the City of Helsinki in Finland. Our goal is to test, if shredded marine/beach plastic litter is suited as printing material. We are aiming to offer this printer to the PP community, since you have the means of producing shredded plastic, but you don't yet have a 3D-printer in your machine portfolio. We have big dreams about this printer, so hopefully we can find our first beta testers among you guys. As for now, we can't tell you any price for the beta kits, since we don't have all parts ordered yet, but we are aiming at a significantly lower price range than printers in this size category usually have. And... We will release the printer open source at some point in near future

So the question is, what would you print, if theoretically anything is possible? (edited)

Here is our Precious Plastic Philippnes first big molding project. We make this item for use in rice mills, it is attached to the grain elevator. However we found other uses for the same item. We have made hydroponics pots, and today we used a bunch of the pots to organize all our nuts and bolts in the shop. 100% recycled HDPE soda bottle caps with a bit of added zinc oxide as pigment. Extruded thru ur modded v2 extrusion machine (2hp 200 rpm) with a v3 extrusion screw. Molten plastic transferred to a hacked hydraulic log splitter (aldi brand) with a water cooled mold made from laser cut steel parts. We use the rejects in other items as they are too thck for the shredder to process well.

@theFLO love this guys! saw that you also made a sheet press. which do you think is beter for making sheets?

@holis Thanks!

We love it too, the first results we got are awesome! We heat for about an hour and cool down for about an hour, so in an 8 hour day we can produce around 6 sheets. We prefer the coldpress over the hotpress, because its just so much quicker! With our hotpress we were not happy because after 1-2 hours of heating we had to do around 4! hours of cooling in the press due to good insulation, so basically 1 sheet per day... MUCH better now

@Susantenhoeve We worked quite a lot with that, i would only recommend it if you cannot afford an oven + small coldpress for sheetpressing, because most of the results we were getting were bad due to lack of pressure. We got way better results with a coldpress system and a 1ton carjack for 30x30cm sheets (edited)

Got my geodesic dome moulds today from Easy Moulds (https://easymoulds.de). Very excited to start making these and get some domes built. I’ll post some updates as this progresses.

I can’t express this with my reaction emoji. So I will say it, this is sooooo good. It was my dream to making something like this. Really well done!! (edited)

@Vudv thank you so much. It was fairly easy to make, i used 2 and a half sheets (my sheets, check how to on how to make) and a hot glue gun. Really appreciate the kind message and have been asked to make a tool box and a few smaller money boxes. So more to come.

Maybe try screws as well to make it more durable? Would look good as well. And to save on materials you could also get rid of the hinge and make the lid a tight fit by adding some small blocks on the underside in the corners. Just shooting some ideas to improve, looks really good already @Zero Plastics Australia

(edited)

@Jonatan | NL I've had issues when using screws but I'll try again and see what I can do. They wanted it so they could open it at the end of the day, but I like your idea. With the money boxes I was thinking about making it fully closed and having a trap door at the bottom but still thinking. Have any ideas on what I could do for that?

Maybe you can make the lid recessed so you need some kind of hook to lift the top of through the slot. To make it a bit secure

2:42 PM

For the screws i guess you just have to predrill and countersink large enough.

Good idea, will test this out

@Zero Plastics Australia Cool stuff. Ever try making a cabinet?

@D●M J■HN na not yet, its been on my mind but will wait till I have a bigger sheet machine.

@Butte (PP Philippines) That was an awesome watch. Makes you feel we are not alone trying to make things change. I really feel the same as Scott although we are in a very different part of the world. Seeing the ocean getting destroyed days after days and trying to find solutions both instantly and in the really long run. I sincerely hope we will be in a similar situation in the years to come. It is indeed incredibly hard and challenging. Thanks for sharing and participating to this work.

depending on the size of a beam how many kg of plastic do you take?

going more industrial... client ordered our shredder with this engine. 2 units

Isn't plastic waste beautiful!

Had some time back in the shed today and smashed out these beautiful new sheets!

Playing around with colours is always fun.

We are extremely pleased and lucky to have a new batch of shredded plastics! These new colours are a green/blue/red mix and a black/grey mix.

I personally love the mix of both! Green/blue/red/black/grey!

We are still taking orders and will be slowly getting back into the run of things. So if you have any requests or questions let us know.

what is the thinnest sheet you made?

3mm but it didn't work well, I find that 10mm works the best. As any smaller I battle warping of the plastics alot

can you vacuum form the sheets, or are they too think?

I think you might be able to do that, but don't have the machines to test this myself. You could make a 5mm sheet and might have a better chance with that

After a sand and an a wipe down with a wet cloth, super happy with these new sheets. Does anyone have any recommendations for polishing plastic sheets?

(edited)

Looks awesome! Is the main wooden frame cut on a CNC router?

@Isometric yeah CNC cut .... the idea is to cut plastic sheets when i get the press done

Let us know your experiences once you start cutting, I've also got a CNC router and would be interested to hear feeds speeds etc

cool ... i believe in 60-70 days i'll get the chance to cut the first sheet

10:59 AM

Some civil engineering students tried mixing some aggregate (gravel) with HDPE. They cut it open with a big grinder. The results are quite interesting, but just be mindful of the plastic dust created in the process.

That is impressive. Do you think it improved any characteristics (eg vibration dampening or rigidity)

@Ben - Precious Plastic Ciledug do you have material property testing abilities with them? (i'd love tensile/compressive strength etc tests of recycled plastic test objects vs "raw" plastic)

You must love what you're doing when it's dark outside on a freezing cold night

, and you choose to spend your time in it to recycle more plastic waste

‍♂️ With our recently received larger sheet machine we are now able to make 55cm x 35cm sheets!

Check out the new sheet made tonight using 2.5kg of plastic waste!

@Zero Plastics Australia this sheets are 55/35 cm nice with this machine

. This is a hot sheet press for clouds. Correct me of i am wrong. This machine have only one surface that become hot? Witch plastic you juice? And How long you have to heat to become this nice plates. (Machine type-how many Watts)Good job met me know, thx keep on going

carbon fiber filled HDPE plastic chair we made today. We extruded the HDPE with milled carbon fiber mixed in. Pressed into sheets on the cold press. Then cut to shape with the circular wood saw. MIG welded a steel frame using about 6usd of metal and bolts. The plastic was final shaped with a flap disc on the angle grinder to round the corners and give a better finish.

6:53 AM

@Butte (PP Philippines) really cool! How long were those fiber you used? And how do the fibers enhance the mechanical properties of the plastic?

> @bloftdesignlab it was really short milled fiber. around half mm. very expensive and super itchy. makes it stiffer and changes the appearance similar to 3d printing with CF filament. I bought a kilo last year for experimenting, just finally got around to using it up.

Cool! I still have a kilogram of 6 mm long chopped fibers laying around. Will try it out once we get the printer ready. Would be great to hit a spot somewhere between CF-filled filament and laminated cf-stuff

The idea has a lot of potential

What’s all the racquet about recycling carbon fibre?

Carbon fibre is an extremely strong, yet light weight material. This means it is attracting more and more applications – from bikes and tennis racquets to sports cars and planes.

11:30 AM

seems to be a carbon fiber waste problem coming our way, so if reused fibers can be implemented in recycled plastics it offers a potential use

@jasonknight these look absolutely amazing! How resistant are they though? The under side of my skateboard (specially the nose and the tail) are very thin and have lost lots of wood. How do these plastic boards compare to wooden ones? (edited)

They are slightly thicker in the middle than the edges to make them stronger, a bit more flexible than wood but you can use this to get speed like a snow board

I'm a little torn with this. Usually I make things in pure plastic so they can be recycled. But the thing with recycling plastic is that plastic cannot be recycled indefinitely....which surprises many people when they find out. Anyways here's something that looks cool and should last a really long time unless someone breaks it.

1:48 PM

Unpacked Volume mixture is 1 : 1 : 1 (cement:sand:hdpe flake), don't make the mixture too wet or else the plastic will float up a bit (ends up on the bottom of the product) (edited)

@Ben - Precious Plastic Ciledug These look great! I was contemplating doing something very similar with thermoset plastics

1

2:10 PM

There's also these 10cm x 10cm tiles. A potential client was asking if I could make a specific style similar to this. Too much water causes it to crack it seems. Some sanding makes these look great. Concrete tiles are a thing so you can look that up. There's also sealants that can be used that would likely lock in a more wet look for the concrete, not sure what it would do over the plastic though

2

@Ben - Precious Plastic Ciledug , cool tiles! You could also look into mixing in broken glass instead of the HDPE. Pretty easy to break up colorful glass bottles

First crude steps at processing PP bags into something 'useful', well not so much yet. Gotta start somewhere...

10:53 PM

it is HDPE bottle caps

@Thomas Peterberns | Johannplasto

> @Mattia We have moved a bit beyond the standard molding practice with the extrusion and compression molding that Precious Plastic is doing. We developed a hybrid process of molding. We extrude plastic into a large blob of hot plastic that we collect and keep hot in a turbo coker oven (25usd) and the plastic sits in a stainless steel bowl that is covered with high temperature RTV silicone gasket material. We then gather the blob of hot plastic which at this point is similar to sugar candy in thickness with 2 silicone cooking spatulas. The hot blob is placed in our compression mold that has a water jacket in the mold to cool the plastic. We compress the plastic in the mold at 3 tons using a pneumatic bag jack (used in auto shops) The plastic cools quickly under pressure from the water pumped thru the water jacket surrounding the mold. The water passes thru a heat exchanger we made from car parts, a pump and industrial fan. The plastic remains under compression for aprox 1 min 30 seconds. Then air is released from the bag jack. the mold is open and the mostly cooled dolid part is removed from the mold. At present we are molding a 215 gram part every 2.5 min. One operator. The mold for this particular part was disassembled last week and we are building a new mold for plant pots. We have a volunteer workaway engineer from South Africa who makes plastic molds in his day job. He is doing the building of the new mold. Working on some more upgrades for the molding machine. However limited due to lack of funds since the covid situation. The next upgrade will be a micro controller and solenoid valve to actuate the air bag on a timer and get a more consistent production. I estimate that it will boost production by aprox 10%

Precious Plastic Philippines v3 Shredder

it is HDPE bottle caps?

@Butte (PP Philippines) Yes

(edited)

Hi recyclators !

Sharing some experiences with Our upgraded version of Injection machine "Elena" from Plastichubcat. We added extra welded construction with wheels with brakes for better stability and usage. Also we switched from M20 nuts coonectors on our moulds to conus connection thanks to 1,5T car-jack. In comparison with classic PP Injection, this version works much smoother, thanks to gears

️ you can bring higher injection pressure, with very small effort. You just feel like a captain during machine operation. For the moulds, we are usually using simple and cheap laser cut mould from 3 parts. During the injection process, while melting HDPE, we are setting first PID controller to 210 C and near out-put we are using second PID controller to set sligthly higher temperature

For fumes sucking, we are using active carbon filter with Centrifugal duct fan 125(green box on the left side), and it works just brilliant. (edited)

The wheels and cart look like a great way to stow the machine in a shop, and store molds. Nice work! Do you know @magi SVK ? Sounds like they are getting started in Slovakia too.

@CitSciWorkshop yes, we are in contact. In fact, tommorow i'll get the whole shredder kit from PP Slovakia

@Martin PP Slovakia We have a Elena too, did put it on some bespoke aluminium step ladder for transport. using it between 145 and 165 deg for HDPE

@Martin PP Slovakia 210 deg and more for HDPE? I use about 155 deg for HDPE and 180 deg for PP...

oO 180 for PP, are you sure? Everthing below 210deg on PP badly delaminates for me.

I wonder if it is not down to the quality of the shred but yes PP melts at 173 so depending where you put your thermocouple, it is much higher temp in the barrel

Hi guys. My products.

@Ken Tran Teo one in the middle is nice!

Is that one part or is it an extra ring?

@Arson Hi! I've seen you've made stamps. I am having trouble stamping my products. Hoy can I make the stamp and then what do you recommend to heat it and engrave the product? If anybody else has suggestions, please feel free to share! Thanks

@Ken Tran Teo one in the middle is nice!

@Thomas Peterberns | Johannplasto It is one part. I and KenTran are one team :) Nice to meet you.

Maybe for some inspiration, this is a hand driven injection machine I made in 2016/2017. It's a vertical machine with a proper clamping unit, capable of holding 5 tons. The platen are made of Aluminium tool plate (5082 if I remeber correctly). The injection barrel is similar of size compared to the PP injection, including a (bronze) plunger. The drive is a rack and pinion type with big levers to be able to inject with good pressure. The frame of the injection is waterjet cutted stainless steel. It it used to produce small productions of caps and key chains, but I mainly use it for workshops and demo's, or to rent it out. The first version had a smal jack to close the molds but I upgraded it to a industrial jack with pump for convinience.

@Bazyaftchi yep, it’s basically clear polystyrene filled with air, these require a large amount of it just for one coaster

hi friends, I'm interested in developing a free application that helps facilitate a healthy recycling community from individuals to actual recycling businesses. I made a Google forms survey to collect feedback and ideas if this is something you think might be useful to you. I'm also open to feedback on the survey questions and format themselves. https://docs.google.com/forms/d/e/1FAIpQLSfjBwLhcPmu5SiinOaYMyZv7p-1QGFFt9BIdlqMj38cW6oPLg/viewform?usp=sf_link

Are there any spaces that would be willing to give us a virtual tour? Our community point is Precious Plastic Seattle, and we're interested in setting up a time to see some mature spaces that are up and running. Ideally, we'd love to see an all-in-one space. I'd be happy to set up the event and post it on the Events page if there's enough interest. https://community.preciousplastic.com/events

@raghav_roxx looks good! Only thing that concerns me is how would you make a corner joint?

I really needed a mallet so I used a large tin that I filled with metres and metres of rope progressively as they were melting in our oven. Went and cut a bit of willow that looked like a good handle. Made a green wood preparation (basically shaving). Placed the handle in the melted PP and let it cool down slowly. The polypropylene contracts very strongly and seized the handle extremely hard. It is a bit on the heavy side maybe Thor would be jealous of this low tech recycling. I suspect it would be better to make it in LDPE for a softer touch but we don't have much of this on our local beach.

Nice @Butte (PP Philippines) , is the motor connecting to the shredder via a sprocket/chain solution? Cant quite see because of the grate

Yes I used sprocket/chain to double the torque and connect it instead of a direct drive. Direct drive is cheaper, but I do not want to risk customers having issues with jams and having to change it down the road.

Here is a mold quick release we did. Welded two cheap vice grips to the mold.

Seems like a great start, I have to say. Needs to use light GRBL programs or something...

I used gcode and Marlin/ramps like a 3D printer to program it.

Awesome, I was assuming that a good injection firmware would strip a lot out of Marlin, simplify and edit out a lot of the motion.

It comes down to what you know. SOTOP is doing great with a very simply interface. @Butte (PP Philippines) and I have been developing 3D printing for over a decade each. :) I'm sure we can all make some great strides in each our own way.

yes the cleaning feels great but it takes more time to collect that much. and thanks for the nice comment

450 sounds about right for something of that size

@Rai really? that hex bowl from precious plastic guys were 350g I guess. compare to that something with this size seemed too much to me. maybe I'm wrong

I would have originally estimated 350 too (edited)

Made these cabinet knob molds on the lathe this week for use with the hydraulic injeciton molder. Aside from the flashing needing better trimming, it came out perfect. Super excited for the results. Next step is to design and build a manually operated mold open and ejection system. Same function as the automated clamping on commercial machines, but hand operated. Work Flow: 1 mold closed via hand crank, like a vise. 2 hot plastic injected in mold 3 Plastic freeze in mold 4 Mold opened with hand crank and ejection pins push the part out of the mold. 5 repeat. Hand operated at first will let us understand the work flow, build it at a lower cost, and product more items which will use more plastic waste AND make the process more economically viable. We are searching for a viable product to make and sell locally.

unit cost or MSRP?

Has anyone used desktop laser cutters on their plastic sheets before? I want to know if its worth getting a desktop laser cutter over a cnc machine for cutting our sheets into more detailed/useful shapes. Merry Christmas everyone - enjoy these beautiful little Xmas trees made from recycled ldpe.

9:26 PM

use an electric saw + catch/reuse the microplastic shavings?

Yeah thats what we have been doing now and the shavings are great for our injection machine, however want to stay away from mircoplastics as much as I can. Yeah Ill take a look at cnc lazer cutters and see what they can do

As long as it isn't a chlorinated/floronated plastic it should just be NOx / Odd petrochemical emissions so nothing TOO toxic

10:46 PM

If diluted + disposed via venting you should be fine given the scale is so small (an ocasional use, not a 24/7 coal power plant)

1

10:47 PM

Still though it is good to consider all the potential issues and not be like "i'm a small operation so no need to worry at all" imo

Thats the point isn't it, to stop it everywhere at any scale

i agree 100%

3:15 AM

but if you want to start a shop, but only have enough for the machines + a box fan, not a fume extractor + treater, i think it has more utility to start and have a small NOx emmission vs leaving the waste to sit there due to no shop existing (edited)

Hi everyone, I believe I’ve seen a beautiful stool made with wooden legs, and another with plastic legs, wanted to know more about those two builds. If anyone could direct me where I can find out more about those builds I would appreciate it so so much. Stop ignoring me .

@Gusta how beautiful, I wonder if you have built a small stool before? And are the legs wood or plastic?

@Zero Plastics Australia how difficult is it to get a plate that nice, what is the approximate time of completing one sheet plate ? and how difficult /costly is the machine build?

@summer not that difficult, we make 330mm2 and 500mm x 300mm sheets with ease. Set up is about $1000aud to set up. Takes an hour to make a sheet

@Zero Plastics Australia I’m finding it difficult to download the blueprints, I logged on to precious plastic page got to download kits, it gave me a list. Then when I clicked on download, it just freezes. Is there another way?

Not that I'm aware

I figured it out, it’s the reader.

Hi everyone, I’m new here. I make jewellery from recycled silver and other materials including plastics at home in my tiny studio. The plastics i simply melt down in a little oven. I have a question and i don’t know where to ask it. Can i use the term “precious plastic“ to describe these items? I dont belong to any formal group, its just me

1

3:16 PM

3

Can i use the term “precious plastic“ to describe these items? As far as I know, the name is not trademarked in any way. (Maybe HQ should review that thinking.

) But anyway, none of the workspaces around the World, are contracted or "licensed" in any way. So, technically, nothing is stopping you from using the name. Would just be nice to give a shout-out to the global project, so that people know what the "bigger picture" is, I think.

1

Thank you @Frederik C (ZA) that sounds like a good approach.

I stand to be corrected. But I think that's right.

In terms of international intellectual property law, if a name is already in common use, I think it effectively becomes impossible to trademark. Possibly only a unique logo could be registered by someone. Apparently, celebrities like Sting and Spike Lee have tried to trademark themselves. But their applications were thrown out, because "sting" and "spike" are too common words for anyone to claim.

I certainly dont want to use the word as if its my own, the global community of precious plastic makers are doing so much more than I can do in my small way, but i’ve struggled with how to describe items, and “recycled plastic” doesnt capture it quite as well as “precious plastic” does, I just don‘t want to misrepresent my work as something it’s not. My ethos is to create beauty out of waste, so maybe I should just keep describing my pieces like that. Thank you for your input.

Sure. PP HQ probably won't care, either way. That's basically the open-source ethos. It's still an interesting question, from a technical, legal perspective. Like, could you start a new tech company, and name the brand Apple? Probably not. But only because there is already such a company that enforces its claim to the trademark. If there were lots of companies with products called "Apple" it would probably be unenforceable. But you could probably have a fruit distributor called "Apple Store" without problems.

Great use of HDPE from Izzy (edited)

Dust collection is great in the shop. We have a 2hp, 4 bag unit on our shredder, that we also use as a way to dry plastic in a large 55 gallon drum. We just supplied a client with their own dust collecting/shredding system, although in the future I think we will build a rolling frame to mount that blower the same as in this video.

Nice build! The level of noise comes basically from the motor or the other moving parts? I don't know how loud it is when standing next to it but it sounds loud in the video.

no, its a light industrial dust collector 60 micron bags. It was sold as a add on to the CNC Routers I was distributing locally for ACC Tec last year. The bags collect so much micro plastics that we can re-use rather than breathing in or making a dusty mess in the shop, not to mention it increases the efficiency of our plastic shredder a good 30 percent (estimated) I think that good vacuum collection system to blow and move our plastics around the shop to handle them will be the next step as we move up our boot-strap precious plastic machines to a legit plastic recycling processing molding shop. (edited)

Ι really support the addition of a dust collecting system, for the reasons you mention! The biggest disadvantage/problem i relate to this is the added level of noise from a second machine's motors. Probably you would have to be working with ear protecting equipment the whole time.

Ι really support the addition of a dust collecting system, for the reasons you mention! The biggest disadvantage/problem i relate to this is the added level of noise from a second machine's motors. Probably you would have to be working with ear protecting equipment the whole time.

Yes we wear hearing protection and dust masks. One day we hope to relocate the noisy machines in a more sound proof area

We are experimenting with adding color back to our extrusion/compression molding process by adding some plastic chips to the oven that keeps the slug of plastic as we extrude enough to mold. We have to twist it like hard candy while wearing welding gloves to get a nice effect.

It's a plastic shredder of our design. We found that the v4 shredder was too expensive, so we had a engineer from the Netherlands come to our shop and design this.

Awesome @Butte (PP Philippines) Is there a write up anywhere or the files so we can take a good look?

It's not open source. However it's similar mechanism to the robot Digg shredder and others on eBay

@Butte (PP Philippines) that's fantastic

do you sell in Indonesia exclusively? Or Asia?

@Butte (PP Philippines) goes without saying that it would be phenomenal to have a how-to about it with technical drawings that people could replicate

Seems great!

This was a bit i was thinking on about the other day, the shipment of Open Source Hardware (OSHW)

8:14 PM

Like when you buy, lets say a 3d printer, from some company you get a fancy box, and it is all packed nicely and whatnot and what to learn/grow on from that

8:14 PM

Granted this is probably better to discuss in #just-chatting or something lol

Looks great for shipping, although to be honest, we have not sold a single sheet press over here. Despite a lot of advertising.

We've been working on a new flatpack version of the sheetpress so we can ship it easier.. what do you think?

Is the hood pretty heavy to lift? Would a customer need special equipment to lift? Been trying to do the same thing lately.

@Michael L You can't make it with molds you need a 3d printer.

Earrings with a cause! Recycling between 3-6 bottle caps per set ( depending on which set you choose ) they are a beautiful little addition to your outfit

sure they are recycling only a smaller amount compared to some of our other products, but they are a great way to raise awareness about recycling, and to show others this proof of concept, that recycling waste can be pretty, it can still look new, and how important it is!! For anyone who wants to join the cause and help us on this ride, we would absolutely love some feedback, and some suggestions on other shapes that you all would wear yourselves as single use recycled jewelry! We hope you like these just as much as we do

we will have them up on our website tonight as soon as the kids go to sleep ✅ well, I will try my best anyway!

First attempt at the plastic brick in our shop. It is more than 1.5 kilos of hdpe to fill.the mold.

@butte we have been trying to make a brick as well with less luck then that. Was temp and rpm is your machine at?

220c 100 rpm

1:56 AM

Under filled, cold weld, hardened before full

1:56 AM

Need a bigger extrusion mavhine

Without pre heating the brick mold in a oven or using a heat gun on it while filling, i fear that the v3 extrusion with compression screw is not fast enough to make bricks.

5:49 AM

Under filling, cold weld, all signs that the plastic cools off before the mold is full. We also bent the mold. It spread open under the pressure while parts were not filled also tbis mold is 1.6 kilo to fill, not 1.5

7:55 AM

With pre heating the mold

@Butte (PP Philippines) we have the pro but judging from this it seems our issue is we haven't been running it fast enough

Did you do a extrusion test?

1:10 PM

You should be running 20 kilo per hpur as per the netherlands group

1:11 PM

V3 maxes out at 6. Tried running faster, but then needing to increase heat and still not satisfactory result, so i slowed it back.

1:13 PM

Pre heating was suggested by a plastic guy who helps me with technical advice

1:17 PM

Second option is filling as fast as possible. Also some concerns about mold strength. If i.make another mold the top and bottom will use thicker material or weld a large piece of square bar on the sides. And designing some sort of fail port. Mold gets full. Plastic gets ejected thru a hole as a visual indicator

@Butte (PP Philippines) we did not do an extrusion test. How would you suggest going about this

Oh thats easy.

2:08 PM

You got a cheap digital scale?

2:08 PM

We use a 15 dollar produce scale

2:12 PM

You can weigh out 5 kilos and time its extrusion however that will not be as accurate as loading the machine and running for like 30 min of extrusion.

2:14 PM

Reason being is that you can hqve delay from time machine is loaded to time plastic actually comes out.

Oh ok I gotcha

2:20 PM

So ideally how fast should it be able to process 5 kilos

@Angus17 Have you tried running Barrel 1 at 235C, @ at 245C and the Nozzle at 255? I've also seen people warming their molds to prevent cold shuts and fill easier.

We warmed the mold but still weren't able to make one. Going to preform and extrusion test this afternoon and upping the speed

@Butte (PP Philippines) @Angus17 what item in your opinion is best made with the extrusion machine if it has issues like these? I have one on the way and plan on making beams mainly, however love the brick idea and also larger pot plants/bins so hopeful that it can make these.

Angus17

Oh ok I gotcha

20 kilo per hour

3:34 AM

up your temperature also

3:35 AM

im running hdpe at 235c and using heat gun to keep the mold hot while it is filling

wish I could help, that’s pretty out of my league, hope you get the bricks working (edited)

Ah, I just saw in the video the guy said the shipping cost more than the machine itself. I also got an email back and they said their granulator didn't work well for thicker plastic and suggested we get their pp style shredder pro box that they built. We don't reshred our thick extruded waste plastic anyways bc we don't want to damage our v2 shredder.. (edited)

have you looked at second hand industrial shredders? I think you were looking at single phase and you will have a hard time having more power. For thick plastic I would recommend more than 15HP, 20 probably ideal. That's another ball game all together. There is no magic really

@Gallon What do you like to do with the shreddes PET? If you need very smal Granulate you maybe need a granulator...

1

Wait,i thought those two are the same?

@Gallon Just in case if you need more like powder than flakes.

Hm,i thought the size of flakes depends on size of blades on shredder

12:13 PM

@Gallon It depends on the mesh under the shredderbox.

That would be sieve?

On preciousplastic bazar i see parts anywhere from 500 (that one is regular steel) euros to 1600 (stainless) There are 2 listings of stainless steel laser cut parts, one being 1000 the other 1600e

At what temperature 10mm hdpe sheet starts burning.?

Pleasantly surprised that I didn't need to 'shred' my PLA pieces to melt them nicely into a silicone mold, I just snipped bits apart and gradually plopped the PLA bits in! Done in regular old toaster oven, about 325-350 degrees, about 45 minutes to an hour. I love how shiny and hard the plastic turned out!

Hey everyone! We just created system which tracks the plastic we used to create our Xmas 2020 products. It allows people to find the product they ordered and then not only see what we used to make it (and where that plastic came from i.e. who supplied it to us and what it was originally) but also to cross-reference that data and see what else we made from the same raw material. We'd love to hear your feedback on it if you have a second: https://youtu.be/Ob-SJ3YCoVw - video discussing it https://coda.io/d/Relic-Waste-Tracker-V0-2_drmavHsvVep/Whats-In-My-Product_suAMZ#_lukJ3 - the tracking tool (based in Coda.io - which is recommend for nerds like me)

Exactly this! Yeh you pretty much summed it all up heh. The original driver was internal; since some of the products we make require lots of different colours, and since a complex order might be for 20 difference products it's difficult to manually compute if we have enough of each colour to satisfy the entire order. The back end of this system makes that problem pretty easy. The hard part is accounting for everything we use - which we're still grappling with. We're hoping it adds value to both customers who donate plastic - helping that advertise that they are indeed recycling their plastic and to end users / consumers of product who can verify their product came from recycled material. Hopefully in time, we might be able to monetize both these systems.

Now that I had a chance to actually go through this entire thing- I really like your YouTube explaining the site- it’s such an earnest approach to the problem. It doesn’t seem overly preachy, it’s just honest about the lack of trust in the system as you said and personally that tone reaches me the most. maybe it’s my marketing brain but I immediately think of how many brands would love to see this tool roll out at sxsw or a pop up at ces etc. or how a collab with an artist who makes a product could make this go viral (which of course isn’t that important) except that it would give this tool crazy exposure

Brilliant! I went back to the graphics and had another look. RE: last one, PET is a nightmare to work with, I wouldn't suggest trying to make sheets out of it tbh. Many have tried and failed hehe! We find most yoghurt pots are either PP or PS, but they're a good source of PP and PP is good for sheets. You might also want to think about PS / HIPS. Although it's smelly, there's lots of it around and it's apparently good to work with too!

Pleasantly surprised that I didn't need to 'shred' my PLA pieces to melt them nicely into a silicone mold, I just snipped bits apart and gradually plopped the PLA bits in! Done in regular old toaster oven, about 325-350 degrees, about 45 minutes to an hour. I love how shiny and hard the plastic turned out!

Very nice work, what was the mold and did you design it?

MystroPolymeric

Very nice work, what was the mold and did you design it?

I did not create the bracelet mold, I think it came from amazon. I did however, make my own silicone mold after this, the 'smooth on brand dragon skin silicone 30', and was pleasantly surprised to see it hold up so well baked in the oven @ 350 degrees fahrenheit. This is Monsier Cycley von PLA, a doorstop I made in Tinkercad.

EUREKA! Finally, after hours of working in the shed last night, my best mate Bird and I have cracked the USB flash drives! We welcome you all to the very first of its kind - Handmade Recycled USB Flash Drive! Before Bird had the idea of creating a recycled plastic USB, we weren't sure if it was something that could be done.. melting the plastic to 180 degrees into the mould, we thought the heat was sure to destroy the electricals. But here we are! After hours of R&D we have made it possible! They contain around 6 bottles caps each and what an excellent way to show others what can be done with what we call "waste" Available in 32GB and 64GB in a variety of mixed colours, and with each one being unique you'll never misplace yours with someone else's!

Handmade wearglasses from HDPE

Congratulations! Do you have blueprints or pictures of the mould? How did you produce the mould?

Thank you. We not yet make the mould for this wearglasses. We trace from the original wearglasses and the we cut it.

mochhasrul

Thank you. We not yet make the mould for this wearglasses. We trace from the original wearglasses and the we cut it.

Nice! They look like they have a pretty good finishing

Must take you some time, right? What tools do you use to cut?

Nicolas Lamoureux (PPYQG)

I’ve made a considerable amount of plastic hexagon tiles and I’m wondering how people who have done this affix the tiles to surfaces / to other tiles. PP had an Instagram update that showed some injection projects and a couple of them were kitchen backsplashes made from plastic tiles. Do people just use conventional methods the same as they would for ceramic tile to do this? (edited)

Nicolas, it depends on the particular plastic you are using. Most likely a grout-type attachment (like what is used for ceramic tiles) would not work with plastics. These type of adhesives rely on "keying" into texture on the back surface of the ceramic tile (this is why the back of tiles are not glazed). Smooth plastic won't offer any texture for the grout to grab onto. So, instead, you'll have to use some kind of construction adhesive. Look for something which is specifically directed toward attaching plastic sheeting for water proofing, or other applications. And if you made your tiles out of HDPE, know that this is an exceptionally difficult plastic to glue, so you may have to either use a specialized adhesive, or flame-treat the surface of the tiles, or both to get them to stick. Good luck, and let us know what you come up with!!

Thank you @humblefactory! The particular type on those tiles is #6 PS. My only issue with adhesive (or anything I can think of really) is that it would basically end the recycling line of these tiles unless you could somehow remove the adhesive after somehow. I’m going to try a bunch of methods over the summer and see what works best. Thanks again and I’ll keep everyone posted.

@похищен nice! what kind of electrical system do you have going on there? We're doing some dev on the Shredder pro to improve it . Also did you have any problems with the build?

No Problems at all. When you work almost all day with Metal, this is no big deal. Motor is 3Kw, hooked to a FVD with Auto reverse and overload/undervoltage protection

@похищен

What's you plan with the shredder? Starting a shredding workspace or do you already have one?

I planned to sell only shredded material. But so far no one is interested. I have Material here, about 3 tons of HDPE. I just have to shred it. Price is 100Kg/400€

Smaller ammount is possible too. 1Kg/4€

I just did something weird. I used some teflon fabric to keep the plastic from sticking to my surface but it also stuck the texture of the fabric to the surface. Some of the plastic did seep through the teflon fabric, but it still didn't stick together.

@Ben - Precious Plastic Ciledug looks good tho, i'm trying to figure out a faster and more efficient way to "iron" foils, and adding this kiind of texture may be nice

Joseph

@Butte (PP Philippines)

Anymore information there? Was the sheet flat? Consistent height diameter throughout? Full melt?

flat yes, and shiny. we did not have any frame on the side, we just loaded the machine and eyeballed the level of the shred layer. however if the machine is closed too tight the frame will flex slightly and leave the center thinner then the outside edges. still more experimentation and practice. but in general one hour and 10 min to do a 5 kilo sheet is the production rate. we developed what we call the 'pizza peel' method of loading the press.

1

3:37 AM

place a 4x5 foot sheet of plywood on top of the cooling press frame.

3:37 AM

place a oiled sheet of galvanized steel on the plywood

1

3:38 AM

4-5 kilos of shred on the sheet, and level with wood, like you are troweling concrete.

3:38 AM

place second oiled sheet of steel on top

3:39 AM

then when the heat press is open and hot, we roll the cold press near the heat press

3:39 AM

transfer the entire sandwich of plywood, sheetmetal and plastic carefully into the sheet press

3:40 AM

then two people with welding gloves hold the sheet metal/plastic sandwich and the plywood is pulled out from underneath the sandwich, just like a pizza

3:41 AM

then the press is closed. gently at first so as to not press the plastic uneven as it is hard

3:41 AM

then as the plastic heats and melts we close the heat press more and more until we have a fully melted sheet.

3:42 AM

you will find that the plastic melt starts slow and increases in speed as you clamp the press tighter as the heat transfer increases

3:43 AM

at 1 hour 10 min we found for a 4mm thick sheet we roll the cold press to the hot press (everything is on caster wheels)

3:43 AM

both press are open at this point,

3:44 AM

we use weld gloves and two people to transfer the hot sheet straight to the cold press. since both are same height, and next to each other it simplifies the process.

3:44 AM

now some observations:

3:45 AM

We think that the cold press could be improved to be all metal and not plywood sheet.

3:45 AM

although the expense will increase.

3:46 AM

but the heat transfer will increase and with a fan on the top and bottom, it could be possible to have a fully cooled sheet every hour and 10 min.

3:47 AM

also if you load your press before turning on in the morning, you can capture what may be otherwise wasted energy and get one more sheet per day.

3:47 AM

also for the final days sheet, we turned off the power 30 min into the process, and let the residual heat finish the job.

3:48 AM

we left the final days sheet in the heat press where it cooled slowly overnight

3:49 AM

Check out our new reclaimed Australian wooden veneer packaging, The timber industry here in Australia have a massive issue with wasted veneer, chucking out tonnes and tonnes of this resource, either to be burnt or buried. Countless trees being cut down for no real reasons... Well like many humans here on the precious plastic platform we don't take that is a good enough reason and have now decided to make all our packaging out of this reclaimed Australian wooden veneer. Showing again that what so many people called waste isn't such. This is all done by a local company here in Australia, if you would like further info on this type of packaging please send us a message or email at zero.plastics.australia@gmail.com (edited)

With a broken ankle, 2 broken injection machines, a busted mould, #237 lockdown and daycare being cancelled, things have been a real struggle lately, however we are not going to let a few snapped ligiments, loose wires, and tantrums stop us from recycling! We quickly ordered in our replacement parts to get Betty going again and we are making some progress on our order for PacWaste Plus - Pacific Waste Management. 500 USB's handmade with the PacWaste Plus name and logo, with reclaimed wooden veneer packaging. These USB's will go out to support PacWaste Plus, the European Union, and Secretariat of the Pacific Regional Environment Programme (SPREP) Funded by SHREP, they were originally trying to find a product using bamboo until they discovered us, and they then made the decision to choose recycled plastic and to support Zero!

️ We couldn't be happier to work with them, and we want to make a huge personal thanks to Nitish for the wonderful back and fourth chats over the past months.

Melting pill bottles into robots. (The Plastic Recycling Episode)

Hey guys, to reintroduce myself after being off this platform for a while, my name is Louise, I'm based in Melbourne, Australia and this year have launched a 100% recycled acrylic jewellery range under my brand name Oh Pluto. I melt press acrylic sheet offcuts into new sheets for laser cutting, and make recycled jewellery as the result. The process took quite a while to perfect as acrylic is surprisingly tough but I'm pretty happy with the result. I've been sourcing acrylic waste from VectorEtch in Brisbane and smaller jewellery makers. I share a bit about the process here: https://ohpluto.com/pages/about-acrylic-recycling-at-oh-pluto

@hikinghack we are in discussions about that type of 3D print recycling in our Precious Plastic Canada Discord. Do you have some more information on the pallet extruder screw and assembly design? Is it a home build or a purchased extruder screw. Also, what is the pellet size it handles? Will repost the cideo in our Discord.

I got the extruder from Recycl3Dprint . It's basically a little metal extruder screw that goes into the hot end There are fans on the side that blow air through the screw to help the pellets flow more smoothly. Our pellets are like 2-7mm handles them well

That is cool. Would it not be better to have the motor mounted higher up? It seems it restrict the print height, or was the attachment and z motion designed like that?

it can go up high, the motor doesn't interfere

Hi . cool machine. Would it be also possible to 3D print, from shredder HDPE, LDPE or PP ? what do you think. please let me know your experiences

Yeah as long as the shred is small enough. Did polystyrene no problem

Toot Toot! By popular demand we are incredibly excited to announce that our new 100% Recycled Plastic interconnecting track, AKA "Track-In-A-Box" is now available! We would love to thank everyone for their kind words and patience with this, it has been a dream come true to be able to create this!

We knew getting into this business that we could never compete with the big named brands and China for price, as each individual track is handmade from single use milk lids that are sorted, washed, shredded, then melted, squished, tidied up and then packed into a reclaimed Australian wooden veneer box that is also sorted, cleaned, cut, boxbro magic and made into a box. Every track counts, and due to the fact they connect to pre-existing wooden roads it only takes one track to educate a child! As children learn by playing they can simply understand how a small choice really does matter!

️ Available as 1 track straight or curved 8 straight tracks 16 curved tracks - when connected makes a full loop! Track-in-a-box! Follow the link to buy your own set! https://zeroplasticsaustralia.com/product/track-in-a-box-16-piece-full-circle/

how do the molds attach to it? threads?

@sponsoons You can either use a threaded mould, or the faster method is to place a car jack under the nozzle. But compatible with both options.

Nice work guys!

@Butte (PP Philippines) Thanks for the mention, super cool to see it in the flesh with the little soap inside

Glad I could be of help!

We have had a little project for schools to stay active during lockdown. I just warn you it is a #FakePreciousPlastic project and nothing is for sale. The project is a collaboration with an artist that is a pioneer in raising awareness about the pollution on the west coast of Scotland, a machine maker that I cannot mention here and another workshop that with which we collaborate. So kids went on our local beach and collected plastic which is mainly ropes here. We designed a mould for skipping rope handles that could be used with most Precious Plastic machines (you just fill it with plastic and close it with a clamp). It is not totally perfect and we are not planning to make it Instagram-proof. But maybe it will inspire some people. We use hemp hopes with it and fill with our injection machine in a hot mould (steel). Surely enough we had fun although it was really hard to achieve.

5:55 PM

lots of possibilities, lots of fails

how it is found, how it ends up

good feel and grip. We had lots of debates on how to make the geometry and the constrain of the draw angle for releasing the plastic

the 4 parts mould. Certainly a lot of improvement is possible but the intention was to go as low-tech as possible. Not that much of a success. The CAD will be released when I will be satisfied with the modifications I am making

Finally finished this hydraulic injection molder. Number 3 of this type built in the shop. Each unit is a evolution in the design. Wiring still needs tidying up, the proper fittings for the armor cable are no stock in the country right now. Got a 4 inch 25 watt exhaust fan to add to the motor to increase cooling and life of the motor. Did some test molding with it. It is enough pressure to literally blow the mold off the threaded steel nipple that connects the mold and machine. Need to devise a pressure overflow or telltale like vents that will signify the mold is full when plastic comes out.

have you or anybody actually ever been able to measure the pressure of any of these machines?

Just math. The piston generates 6 tons. 25mm barrel, so.calculate that way.

sponsoons

have you or anybody actually ever been able to measure the pressure of any of these machines?

Re-purposed "Load cells" / Weights can give you an idea. The structure as shown above may withstand around 2-3 tons. That is the power of a v4 extruder, at a 1:20 1:30 gearbox (felt). Things can get tedious since BSPT threads can fill up with plastic on such pressures, slowing down the cycle.

The hydraulic molder has so much pressure it blew the mold off the machine and shoot it about 1 meter away. M14 threads on a grade 5 bolt stripped out.

@Butte (PP Philippines) , Colin Furze added some limiters/valves to keep the pressure in check ("shop press"). I never liked hydraulic regarding injection, too much brute force and the need to dose things isn't speeding it up either ...

What would you use other than hydraulics?

Rack and pinion can be quite powerful, and if you're lucky hollow shaft steppers with lead screws can work to. Doing manual give a good sense that things are alright though. Let's keep this channel chat free

You screw the mold into the nozzle, but it seems once injected that the mold is ejected or what i'm missing? It may be when the mould is full is opened by the plastic so no screw area is left?

yeah, same question here

try dosing the barrel with 30g each time, rather than overfilling it. It will be safer for your team and will reduce the wear on the mould. @Butte (PP Philippines)

Pp melbourne really has a nice method of attaching the mold to.the machine. Mine has essentially a split nut. Theirs uses a standard nut that can be cleaned out at the operator leisure. Just use a new nut for each shot

Yes, that's right. SMEs and upwards seems to have a longer breath, also enabling them to actually implement new legislations. I was referring more to the educational and NGO sector. This camp is usually the first to go. Covid measures hit lots of SMEs and I don't see Gov. interested to improve things back to normal. I guess that 'climate change' is being used to make things worst.

With my process, it has also been important to work zero waste, and finally this month i got rid of all trash cans in my workshop, and went zero waste in my production. It was also important for me not have a very rigid process and be able to produce a new shape or product, within a day, in order to allow for maximum creativity and just let my imagination flow :b Below is pictured: a fruit bowl, a big floor vase and a lamp.

Hey, thanks for clarify it! Yes the weight is a topic when its come to recycled plastic, mainly in those application for wood replacement, in that case, metal. There is any test done to create beams with will contain also AIR inside of it, like industrial injection molding machine does? this increase hardness of the product and reduce the amount of plastic needed.

Not really. https://skepticalscience.com/print.php?r=448 And volcanoes add to the atmosphere something like nothing, compared to our emissions. https://unric.org/en/even-volcanos-do-not-surpass-the-human-contribution-to-co2-emissions/ Please, stop spreading wrong data.

Surely smoking volcanoes must be a major contribution to climate change? Perhaps, but they are dwarfs compared to human activity.

I did just a little try (my machines aren't complete) as christmas gift to my girlfriend. The mirror is laser engraved by a friend, I made the frame. Just a work of melting, pressing and milling some HDPE. I have to make or buy something better than my manual milling machine to do those works, in the future.

Tip for the day: wait until you've finished painting to crack open the bottle of wine! I bought this beautiful cabinet off marketplace (Facebook) with the plan to upcycle it.. in the process of doing the doors I smashed the glass!

‍♀️ ZPA plastic sheets to the rescue! I decided to replace the broken glass with our recycled sheets. Its now toddler proof!

Just an example of the many different ways you can use these sheets, it's just up to the imagination! Zeroplasticsaustralia.com

working on recycling straws

3:17 AM

i can't stop people from using straws but I can try to stop them from going to the trash

Plastic straws are banned here

They should be banned everywhere

I definitely agree but they're not banned in the u.s.

I think there is a small angle to be made for the disability community in that straws / bendy straws can be of use. This excludes a large amount of people, and non-plastic / bio-degradable and/or (easily) compostable options are expanding. I am kind of in favor of the "make them not the default, people must request them" policy, as well as maybe just investing in, then mandating only using bio-alternatives. Granted Fast Food (despite being somewhat essential for the working class i guess, can't make elaborate balanced meals when you have no time to do so (although not having time is ANOTHER issue i guess lol) is almost always going to be unsustainable overconsumption in of itself, so that is an aspect as well (although Harm Reduction is a valid argument) ) Also proper recycling and/or disposal schemes are a really important aspect to "litter" / marine debris prevention. Granted they would degrade, but littering/open dumping of bio-alternatives would still have some form of negative impact! Typical me overcomplicating the issue, but i guess, as always, there is a bit of nuance over just a ban / that ban being the main action needed (ie more systematic + institutional change is probably required over bans + individual action) (edited)

oh yeah I definitely agree with that. who needs to use straws please go ahead

Hi all! Sam from Portland, OR, USA here. Wanted to share my progress on the Trash Printer I've been working on. It's a large format direct flake extruding 3D printer. I'm using #5 polypropylene, with a 1/4 shred, just as it comes out of my PP shredder. No filament required

The parts it can make are simple and low resolution compared to most 3D printers, but they can still be quite complex, and they also print faster, and are really strong. The extruder design was based on the original PP extruder, I just made it smaller and put a stepper motor on it, and then strapped it to a robot. You can check out this whole album of stuff I've printed so far here: https://photos.app.goo.gl/6bn9rcDURBnbwnBR8. I've got a community how-to up on the Precious Plastic site, and you can watch the tutorial vid for the extruder here: https://youtu.be/plLaYA2nOz8.

Do check out that “Flipfloppi” project! Although do you mean a more conventional “Rowboat” ? I was looking into designing a FDM Printed Modular Kayak once, but got overwhelmed by the complexities of hull design! Could just wing it and iterate based on prototypes i guess.

I've only just recently been able to make waterproof prints, but it is possible with the Trash Printer. A thick base, lower layer height (0.3mm works for me), and two perimeter walls (4mm nozzle) helps make sure there are no thin spots or holes that water can get through. Printing a whole boat would be quite an achievement, but if you had a big enough CNC table and a lot of patience, it would say it's technically feasible. One of my long term goals is to print myself a surfboard, but I still have a long way to go.

@DisruptivelyUseful really cool! I love the large bed size and that you built the extruder and 3D printer as part of the same machine. I'm working on an extruder with similar elements that creates 1.75mm filament, but I'm having some trouble with the electronics. Any chance you have a video on that part of your machine that I could leverage? got a Mega 2560 + Ramps 1.4 board, but I'm concerned I'm going to fry the board. Many thanks!!!

This is my Noztek Filament system, used to extrude rPET filament from food grade pellets that we produce from PET bottles It's not a perfect system and I had to modify quite a bit to make it suitable for PET but now it works nice enough I've also been attempting to buy a pellet extruder printhead but that has been quite a story that makes a company that had been discussed here previously look very bad.

Niice! Do you have that documented somewhere? How consistent is the filament quality? Did you test it for 3D printing already? And how big are your shreds? Any challenges/improvements remaining? Sorry for all the questions :)

Currently writing my bachelor's thesis about it but I suppose I can give a short overview over the changes made if you are interested I've been using it in my printers since before the quality was good, which was like 9 months? Biggest issue was ovality of the material caused by not hot enough cooling water Filament consistency is acceptable but not good, still working on making that better. Currently I can hit +-0.05 on shorter stretches of a few meters, +-0.1 over the length of a spool and I stop spooling and cut out sections beyond +-0.15 I do not shred, or at least i don't use shreds for the filament. We have a PET recycling machine that shreds 4 tons of pet per hour, but the flakes would be a bit too large to comfortably fit into my extruder without intervention, I use under water pelletised material that we extrude. The material is around 2mm in diameter and every single pellet had the same weight - it's food grade material I'm still working on making the consistency better, and I'm also in constant contact with noztek and they are also improving upon the programming of the machines. Also my extruder died on Friday and I'll have to troubleshoot that

@sioux612 super nice and compact

Hi everyone, I had a question about getting a shredder and extrusion machine. I know both of these machines are extremely expensive, so I was wondering if there was some sort of alternative that I could us to shred plastic and extrude it. Also, would it be possible to make moulds out of metal. If so, can anyone give some advice on how to make a mould?

The rest of the prints are usually quite good, but get ruined by a bad first layer. What's your secrete and whats your settings for printing with PP flakes?

Try using packing tape! I've had great success with the Gorilla Brand Ultrawide Premium packing tape rolls. It bonds great and opens a lot more options for print bed materials. I'm currently using a mirror, with packing tape on it. Glass and mirror makes it really flat, and the tape makes it bond. Using tape creates a bit of waste but I've found that the tape is often reuseable, and it's so worth it for good adhesion. Previously I had some success with printing onto a bed of polypropylene bc it would lightly fuse at the right temp, but it was finicky and didn't work as well as packing tape.

Wanted to show off this Trash Printed wind turbine I printed last night! This is one of the best/largest/most complex prints I've ever printed with the trash printer, and I printed it out of my real actual trash! It's all #5 PP takeout containers, coffee cups, and other PP trash that I saved and then shredded up with my Precious Plastic shredder. Now I have a wind turbine! The total energy consumed in the process of both shredding up the plastic and then printing it into this turbine worked out a roughly 1 kwh, and generally I'm seeing an average energy cost of 0.5-1 kWh/kg, not including shredding. I have no idea how that compares with other recycling methods, but it's cool that I can finally measure the total energy cost of the whole recycling process. Anyone else calculating how many kWh/kg your recycling methods take? It would be cool to compare notes!

Is that a direct pellet/shred extruder or are you making filament first?

waterppk

Is that a direct pellet/shred extruder or are you making filament first?

It's a direct flake extruder. I gave up on trying to make filament. It's basically just a the original precious plastic extruder design, I just put on a vertical axis and used a stepper motor (NEMA23, 15:1 reduction) so that it could be controlled by existing 3D printer hardware. The printer software/hardware thinks its pushing filament, but its actually turning an auger. It took me years to dial in the settings to get it working right, but now it's working well enough to make quite a range of useful stuff. It can't make objects anywhere near the detail of a regular 3D printer, but the objects it can make are big, and VERY strong, like, can't-break-them-even-if-you-really-try strong, more comparable to injection molded parts than most typical 3D printed parts.

And here's an overview of the general design: https://vimeo.com/341913802'

that's awesome, that's why I was asking we built a filament extruder many years ago and it was a PITA to keep from getting trash clogging the extruder

7:06 PM

a direct extruder makes a lot of sense but would definitely be a PITA to control

waterppk

that's awesome, that's why I was asking we built a filament extruder many years ago and it was a PITA to keep from getting trash clogging the extruder

If you build one I can help you dial in the feeds and speeds. It was a PITA to figure out, hopefully I can make it less so for others. I just recently got the "Extra length after retraction" feature tuned just right, so it pauses after travel moves to let the extruder "catch up" and start pushing plastic before the nozzle starts moving again, and that has led to a big improvement in the complexity of the parts I can print. Previously I was only getting reliable results with "spiral vase" type prints, but now it's doing pretty well with complex travel moves as well.

I was actually able to print a few of the parts for my new version with the old version, and that was pretty gratifying. I was even able to print a new sieve plate for my shredder when my original metal one broke. You can check out my progression in this google photos album: https://photos.app.goo.gl/6bn9rcDURBnbwnBR8

nice! I'm really surprised by the print quality running a wood auger bit backwards

I can see why you need to pre-spin for pressure/etc, it'd be interesting to get a proper multizoned compression screw in there

Which machines did you use for recycling? Known brands or self-built stuff?!

@DataWorm (PP Berlin) PP pro extruder but all the other machines are self made, took me months to get consistent diameters.

2

I can imagine, but nice to hear that you were successful. Filament production is something that PP is lacking atm

I have PLA that needs recycled. My waste management services won't pick it up. I don't have much, maybe 10 pounds of waste, but I don't want to just throw it away.

@Goldenghost10 I don't mind trying it, and I can send you back a spool if the material is clean enough and shredded.

So I have to shred it myself? What's the best way to do this?

It also depends how far I am sending the scrap. If it too far, it may not be sustainable with the amount of filament I have.

@Goldenghost10 I buy it straight from a big recycling company for 3,2 euro per kg ex vat, small amounts are simply not worth it. I tried from various companies but for 3d printer filament you just need very high purity and that doesn't go well with recycling, 1 grain of dirt is enough to block a 0.3mm nozzle on a 3d printer.

I was wondering about that, we tried making printable filament but it was a huge pain with clogs constantly I ended up using a huge printer nozzle to make it work

@waterppk Yeah, had the same issue, just find a supplier that has the cleanest material, or you need to use unrecycled plastic.

With some plastic material/process settings there were also a few bad ones. Later we also made performance tests with them by trying to break them. Not scientific numbers however #nextlevel

i think something that could make it last longer would be to make a little belly inside the carabiner to limit the opening, bc some people are very good at just playing with it by opening it all the way, which ends up wearing down the flex point much faster

Produced quite a lot of recycled 3d printer filament, now need to sell it or find resellers haha.

I would like to test some and perhaps resell it here in Germany, people has asked about the consistency of the filament. I have no experience with 3D printing, but see that is a good product option.

@Lixeiro Awesome, I send you a message

@Lixeiro super cool. What material are you making it with ?

3d printing filament if you want to make the high detailed stuff you need a extremely consistent product with a very low diameter tolerance . For larger basic models cheap recycled plastic into filament from the extruder should be just fine

2:31 PM

The latest comments in #archived-3d-printing is about the very same thing I made a comment about I noticed

Just started to press some simple parts. I decided to follow my own path, since I want to try keeping the marbling effect of the oven molten and hand mixed plastic, I decided to build a compression molding system. So I made a wooden furniture with a kitchen oven (with an electronic controller with K thermocouple), in wich I put a serpentine heat exchanger, with a rotoflow pump, a radiator, some fittings and valves, to heat and cool moulds, on top of the system I put my press, at now it can reach up to 2tons of force (if needed I can double that value). I made the first try in last days, with a cold mold since for those parts I didn't need a perfect surface (those are parts to be lathe machined) and since making molds with heating/cooling circuits is complex.

2:36 PM

2:37 PM

Need to heat the molds to achieve better results.

2:42 PM

Parts made with blow molding HDPE (dark grey), injection molding HDPE (red) and polypropylene (mixed red/black, green) and some mixed material I accidentally mixed together after shredding, some boxes of HDPE/PP and a little PET fell on the ground, tried to separate them by density, but the small dimensions of the flakes carried with them a lot of air, making the separation not precise, for the white one. (edited)

Those parts are solid cylinder, 78mm diameter (80mm mold), 25mm thick. The central hole is made to center them with the tailstock of the lathe against the chuck to cut the diameter to 75mm, after that a hole in the center has to be machined, they are the base material to make the rings I need to keep long bars in the lathe at job. Since my employer allows me to make about all the custom parts I made for the project for free (all the press parts and the shredder are made on my design), I have to make something useful for the factory...

Precious Plastic molded pot vertical garden has been providing this much food 1-2 times a day for quite awhile now. Super busy in the shop with paying orders so not a lot of time to mold plant pots to finish the build. Today will add in a proper mist irrigation system to decrease the workload, and to hopefully lessen the tendency of washing the nutrients out of the pots with heavy watering. We are pretty excited about this project, as we convert our house from a consumer of resources to producing food, electricity, and many of the things that we currently have to buy. Cutting out the middle-man with more self produced things enables us to have a better lifestyle and not so reliant on cash. Furthermore with the current world food situation, we really need to produce on our own and not rely so much on the corporatist monopolies that get a commission on every bite of food we buy from the stores.

Our new extruder design based on the V4 screw is still being tested. It has been a couple of years we are on it but we hope it will be a game changer, cheaper to build, to run and increased production. Today I reached an extrusion at 150 RPM, I am hoping to reach 300 RPM (for the screw of course). We are writing an exhaustive documentation that will be opensource. We will also provide a lot of code that allows to simulate plastic extrusion (as far as I know that is not available open source) but also to run and configure an extruder similar to ours as it is autonomous and can be run remotely. We are trying to organise a talk where all the features and documents of the machine will be presented before the summer. Ciao

I successfully 3D printed my first "thing" out of HDPE flakes last night with my Trash Printer. I've been using Polypropylene for years, and it works well enough, but HDPE is even more difficult to work with. It prints with the consistency like old thick toothpaste, even at high temps. But I really wanted to see if I could manage to print anything useful at all with it, since it makes up such a huge portion of the waste stream. (edited)

i am interested to learn your output per hour, rpm, heat input and barrel design. At present I ran a v4 30mmx750mm screw in a 50mm OD barrel with 5hp. ran into issues with keeping the heat high enough at a lower RPM.

there are some issues with the V4 screw, the initialization is tricky to say the least. Also using 5HP Our barrel is too thin (c. 40mm) At the moment output per hour is inconsistent so cannot say much about it. I am still adjusting stuff.

In last days I made and tested my first mold with heating / cooling fluid passages. Since I made it on my bench milling machine in my garage, I had to make something small and simple. I decided to try to make a mold for knobs, mainly because I have to give my girlfriend some motivation to keep me at home rather than send me to live in my caravan, after over a year in wich I'm collecting plastic and making a mess in the garage ... I decided for knobs because I made also a plastic board and it has the right dimensions to become a clothes hanger, with the right knobs. I also want to see if with the compression molding I can fill a mold with "deep" holes. in this case it has a depth of 19mm for a diameter of 14mm in the larger part and 10 in the narrower one. Seems working.

Any more feedback about the V4 screw? Inconsistancy in troughput could have multiple reasons beside the screw geometry alone. Material infeed, granule size and inlet temperatures are factors. Also the type of die / mold in front of the nozzle is a factor. Pinching the nozzle (using a valve or orrifice in the nozzle) could increase the pressure in the screw and helps increasing friction. The screw hasn't been changed since the publication of V4 so a review of the design and optimation could be interesting

DataWorm (PP Berlin)

nice, how thick is that sheet?

Just pressed (in the first photo) is something around 10~12mm, the "mold" bent slightly because I put it not centered under the press. In the second photo, after planing, is around 6mm. It is far from perfect, in the photo some defects aren't visible. There are some bubbles and the surface is rough in some parts, but...it is the very first try, I have to improve!

Looks nice, but I fear for thicker plates it might not be transparent enough anymore

It's less a question of the material itself, but more a question of thickness and density. The thicker the housing, the less frequencies pass where they shouldn't.

We have been hacking a lot around the control of the new extruder and we now have a satisfactory alternative to the solid state PID etc The current machine is run by a pizeroW of 1st generation that collects the data and regulate the heater voltage through micropython scripts and library. We control the conduction angle of the heater which allows to send only the exact right amount of energy to the extruder and to preserve your equipment. I remind that the standard design is a on-off switching control. The communication is made through wifi via MQTT to a server in the workshop. The server helps controlling and adjusting the parameters but the extruder is autonomous. The server is in Dash with a plotly GUI. All in all it is a serious energy saving and also a saving in terms of hardware, hoping to lower the building and running cost of the extruder V4. Somehow it sounds more low-tech to us (edited)

And here's what I made for today. For some back story, I normally would make coasters in silicone moulds. They look nice but functionally, they sort of just hold the water from the condensation on the coaster which I'm not a big fan of. So I used my cnc machine on some sheets to do a pocket cut and slip in some laser cut cork. Came out nicely.

Christian is running the extrusion machine. It is using a 1.2 meter extrusion screw, and 3hp 3 phase motor. We do not have the mechanical stirrer in the feed hopper yet so he has to constantly watch the feeding of the plastic into the machine. Hopefully next week we can get that installed and make life easier.

ah so im not the only one with this problem

200 kilos of plastic arrived today. We are approaching half ton of plastic beams from the improved v4 extrusion machine. We was in hurry to get it running so it does not have the safety covers and looks Frankenstein like.

Great post, kudoz to you and the rest of the team, Butte!

So what's your average RPMs for that stuff, .. ?

Cnc'd moulds are expensive. Grinding on a steel plate is not. If you need a pattern on your surface of your extrusions, you can use a steel plate insert. Quick and dirty but it works.

3:35 AM

1st photo = Lines drawn on steel plate. 2nd photo = lines cut out of steel plate, not all the way through of course. 3rd photo = Results. Some ink from my pen that was on the steel plate transferred to the plastic but you do see a raised surface from where material was removed from the steel plate.

The steel piece is inserted into an extrusion mould on one side. I haven't tried more than one side for this.

I like this style of working this out a lot, even if i own a CNC. I think patterns ofter are plus, and getting things done with simpler tools also is a plus, thanks for sharing

@Kat @Joseph @Hugh Just FYI, those sheets were made by these folks : https://www.instagram.com/yayasankakikita/ And they have a very interesting story too. I haven't visited them yet but I've contacted them. They use large ovens to make sheets and make different products from the sheets. They take the profits they make and use it to help people with diabetic wounds and people with missing limbs.

Many workspaces produce products for clients but clients dont aways give credit to the workspace. If you're a workspace, you should have an agreement to include your workspace in social media posts, otherwise you get left out of the limelight.

@Ben - Precious Plastic Ciledug so good! Is that a plynth or something?

Not sure what a plynth is. I think the name for this is router table. A router is mounted underneath and exposes the router bit on the surface. This allows for some easy routing work. There's a lot of how to videos on how to build these but it's all with wood. So this is a little quick and dirty. I'll be putting this to work tomorrow.

I wish I made better photos but you can make sheets that have layers of color so when you CNC your sheets, you'll have an extra layer to be creative with.

it is 2x4 wood size 28 inches long. we extrude the boards about 6 feet long, chop them into pieces with the miter saw, wood plane, and when we have enough they will be assembled into sand boxes that have 40 kilos of plastic each. they should last decades.

This is my Noztek Filament system, used to extrude rPET filament from food grade pellets that we produce from PET bottles It's not a perfect system and I had to modify quite a bit to make it suitable for PET but now it works nice enough I've also been attempting to buy a pellet extruder printhead but that has been quite a story that makes a company that had been discussed here previously look very bad.

We sourced 300 kilos of PP films and HDPE bottle caps yesterday at a cost of around 45USD. No one here recycles plastic films and they are either sent to the landfill or they go to Cemex to be burned and traded for bags of cement. Consequently the PP film plastic are only 5 peso per kilo.

How are you bulking the films to extrude/shred/process them? I thought the issue with films was they clog the shredders and have lots of air in them so they're hard to process

36 seconds plastic lumber

running some HDPE lumber using the pigment idea from @Ben - Precious Plastic Ciledug we shredded and put the pigment in the granulator while shredding so as to get the pigment a very even coat and stick well to the flake. Even so we do have a hard time getting a consistent color over a couple hundred boards. Black is the easiest to achieve consistently and we prob will abandon any other color except black unless we charge a hefty surcharge for the hassle.

For better consistency you'd have to extrude as filament, shred, and then extrude again. I've done this for making black plastic but it's a bit time consuming. I think your results look great, but i suppose it depends on how picky the customer is.

Wait? What

For a color that is more consistent, you can extrude the plastic with pigment as a filament first, shred the results, and then extrude again but into a beam mould.

he is correct, although i do not have capability for filament right now

Butte (PP Philippines)

he is correct, although i do not have capability for filament right now

I don't think it needs to be extruded to filament, I think the key is doing a double shred/melt cycle to homogenize the pigment throughout the plastic

Butte (PP Philippines)

he is correct, although i do not have capability for filament right now

well by filament i dont mean anything consistant, although now that i think about it, you could just run one of your extrusion machines and see what happens if you extrude it to another extrusion machine hopper. that would save you from the extra shredding step haha

For example something like this: https://www.ebay.de/itm/Transferpresse-38x38cm-T-Shirt-Presse-07036-Textilpresse-Schwenkpresse-Textildru/170655070961. We're not sure if both sides are heated and if it works in general.

@Susantenhoeve We worked quite a lot with that, i would only recommend it if you cannot afford an oven + small coldpress for sheetpressing, because most of the results we were getting were bad due to lack of pressure. We got way better results with a coldpress system and a 1ton carjack for 30x30cm sheets (edited)

Hey I m interested in this topic, would you like to share a bit of your experience about it?

How did you do that

5:39 PM

How

I have no idea

happens when you put another color. probably the way melted plastic is flowing through mold.

The plastic cools down in the edges first so the new material starts flowing through the warmer inner part

Hi, we have tested T-shirt press, and came to conclusions its NOT suitable for sheet pressing. Maybe it was just our case, but our sheet press was heating only one plate (from two) therefore sheet was melted unevenly, so result was far from good. also pressing force, was not directed in a good way. So we prefer mould+oven+ cold pres.. for more optimal results. in case of A4 clipboards for example, and its working very good with oven. Oven is providing oprimal heat source, from all sides. In comparison with T-shirt press, its coming just from one side (alteast in our case of T-shir press) Conclusion: NO

the conclusion is similar to mine, but in another hands, for a exhibition and teachings is a cheap and mobile option. I m using PS and I quite like the result. Still didnt cut or done anything with the boards. about this I can report soon. Thanks fro sharing!

i used a tshirt press that worked fine for 3mm sheets. The mould i had was oversized for the press too, but i would just move the plastic and mould around so it would heat up everywhere. I would even remove the mould and plastic from the tshirt press, flip it upside down and put it back in. no problem. Is it the best way? It worked fine for what I was doing and didnt require any modifications. All depends on your learning curve...sometimes we luck out and get good results early and dont have to have a long struggle with failures.

we adapted it for 2x4 plastic lumber and the top is 1x2 plastic lumber, we used black drywall screws, and we counter sink/pre drill for the screws. We also used lock washer on the bolts, and the ends of the table top are tied together underneath with a cross piece of 1x2 board attached with screws from the bottom. Overall it took 2 people about 8 working hours to assemble as it was out first try. We used a miter saw, and cordless drill for the tools, We did smooth a couple boards with the wood plane as they had rust stain from the mold in the plastic.

The black oxide coated drywall screws won't last very well outdoors, if you can use clear zinc coated (silver) they'll resist rust for many more years

I discovered precious plastic for 2021 and it really allowed me to open many doors in my life. Hello community, today I want to tell you something that I am very proud of. All of us who are part of this community know how difficult it is to move from the theory of recycling to action and even more so, to achieve success. In my case, there were some slightly heavier difficulties. I was born and raised in a deprived neighborhood, in Rosario, Argentina (the city of the champion Leo Messi). But still, I was able to found Fenikks. At fenikks we transform plastic waste collected in neighborhood clubs into soccer shinguards. We apply a model one for one, in which for each pair sold, we reward each footballer with another for taking responsible action with the environment So how I tell you my story, I decided to do it through instagram and linkedin, and the video reached almost 4 million views between both networks, which gave us great positioning and opened up many possibilities. Really precious plastic is part of this I share it simply because perhaps there is someone reading doubting whether to start in this world. It really is worth it, I tell you that I started with more doubts than certainties I leave the video so you can support it https://www.instagram.com/p/Ck0tklnPqwK/ https://www.linkedin.com/posts/tom%C3%A1s-machuca_empresab-tripleimpacto-reciclado-activity-7001220420498534400-Whb2?utm_source=share&utm_medium=member_desktop @Mattia It would be great to publish it in English in collaboration with @realpreciousplastic (edited)

Hey tomas! What an amazing project. I remember seeing your shinguards on IG and was very impressed. I am glad your project came to fruition

️ Would love to learn more about it and how we can support you further! Moving forward in 2023 we'll try to reward people sharing their knowledge and contributing to open source so as @Carolina was mentioning it would be great to help you create a how-to guide so more people can replicate the shinguards all around the world

Rory - Sustainable Design Studio

Nice, how did you do the numbers?

We had the mold machined by a place in China that was able to CNC the debossed numbers. (I think it takes something like a five-axis CNC or something exotic like that, to come at the faces at an angle around the numerals.) The ones in that picture are simply filled with latex paint, which does not adhere well at all to PP, so we've switched to permanent marker (especially metallics work nicely). Ink inside the numbers, then sand the flat surface to get rid of the inks that go outside the debossing. (edited)

green is old plastic school chairs, the remaining is soda bottle caps. instagram nice pics coming in a few days, once I got time to take it to the park for some pics.

I’ve made my chairs from banana’s plastic bags, that’s why I kept the colour, if you build furniture with just bottle caps it means you really don’t have a large scale production. In my area before I started there were between 27 000 000 to 36 000 000kg that used to be burned with my project I’ve re used 1 200 000kg just this year hope I will reach 10 k tons

im only averaging a ton a month or so right now. i started out with no money and am slowly earning and building my shop. also covid lockdowns here pretty much made me lose 2 years of my life. We had the worlds longest continuous lockdown, even longer than china.

Gaming dice! Our eight-sided dice injection molded from recycled polypropylene.

congrats its look amazing, can you please share the mold? or the way you build it???? it could be great to replicate in Argentina!

This mold is designed to fit a PIM-shooter 150A injection molder (https://www.techkits.com/products/model-150a/) that we bought used. We commissioned a machine shop to design it and mill an initial simple octahedron without numbers. He also designed a 3D model that included the numbers, but we had to go searching for a shop capable of CNC milling those angles. We ultimately found a place in China via Etsy that could do it. Something like a 5-axis CNC? Then we had to have a staff person learn how to convert the STL model into a STEP file that the machine shop required for the CNC work. We spent maybe $800 total on the design and first aluminmum mold (no numbers); then the Chinese aluminum mold was $230 (plus shipping), not counting our employee's time in doing the STL/STEP conversion (which was really an investment in how-to knowledge for us). Not sure if we'll sell enough dice to recoup the investment! But the important thing was to demonstrate it can be done, and to learn what we did by going through the process from concept through dice I was selling at a game convention this past weekend (it was our #1 item at Con of the North) . It's one thing to ask people "would you like to buy recycled gaming products?" (anyone can say "sure!"); another to ask "Will you hand me that cash in your wallet for this item in my hand?"

10:14 PM

We're not going to share this mold, since it is designed with our replay workshop trademark/logo (like my avatar) in place of the number 8, but I have the impression that the basic shape is not unduly difficult to make in 3D modeling software. Also, you would want to design a mold that works with a larger Precious Plastics injector. (Our little benchtop model has an 18g maximum shot; our mold makes just two dice at a time.) But we are intending to work on more molds and different polyhedral dice. We are also interested in collaborating with any PP workspaces who have tabletop game-related products, since we have sales/distribution/logistics capacity to specialty game stores and consumers worldwide.

I think more than likely people here are interested in seeing how the mould physically looks, getting the die to release from the mould is part of the trick so seeing the geometry/where it's injected is part of the magic

cool, so that could be done on a traditional 3 axis CNC and probably a fiber laser engraver to etch the faces

metal mods have to be pre heated and sprayed with a silicone release spray before you can work with it

This is the way it came from the machine shop. Our guy who did the conversion from STL to STEP did not nearly do the sprue/gate stuff big enough; I used the mini-mill to cut proper channels.

10:22 PM

We chose the octahedron because it has that flat plane interface between two pyramids, which simplified things. It can help to pre-heat and apply silicone, but we don't always do that. There are a bunch of things I would revise on this mold -- I thought it was a good idea to have the plastic come through a vertex at the end of the die rather than in the middle of two intersecting faces, but I think that actually does not work as well (or is a bit more work to clean up, surprisingly). I will see if I can get a pic of version 1, which was made last summer by the guy who designed the model for us (and who had more knowledge and experience of actually making molds):

running some HDPE lumber using the pigment idea from @Ben - Precious Plastic Ciledug we shredded and put the pigment in the granulator while shredding so as to get the pigment a very even coat and stick well to the flake. Even so we do have a hard time getting a consistent color over a couple hundred boards. Black is the easiest to achieve consistently and we prob will abandon any other color except black unless we charge a hefty surcharge for the hassle.

niceee! whats the idea with the pigment? for the colors?

We finally upgraded our wood planer to make a smooth plastic board. Client requested smooth. With our upgraded system we made 500 kilos of lumber in 3 1/2 work days, to include the planing and trimming to length.

client loved it so much she doubled the size of her order to include a batch of grey

Our formwork project has produced it's first full wall.

https://community.preciousplastic.com/how-to/modular-interconnecting-formwork we just published the how-to!! Thank you @Mortar Art (Melb, AU) for sharing your knowledge

Modular Interconnecting Formwork

This tutorial will explain, in general terms, how to use bricks to build a formwork for construction with concrete. Formwork functions as a mould for poured mediums in the construction sector, and in this case, the bricks function as a removable and reusable tool.

Yesterday I made a couple of succulent plant pots for a new friend coming in the hackerspace in which I'm developing the project. Seems that fuchsia pink has lots of fans.

5:42 PM

I found that injecting with a small nozzle seems working better, I forget to change it since last injecions (keychains), there's a lot less air bubbles on the surface.

Interesting

I guess it is probably because the plastic is more compressed before being injected. Do you also observe more pressure / force required from your machine or that the injection is slower ? Or is it not significant ?

I noticed just that the pressure during the injection is a little bit higher and the injection time is a little bit longer, but I think it is normal since the passage area from a 8mm diameter nozzle to the 3mm one changes from 50mm² to 7mm². However having the injector mounted on an hydraulic press the difference are small. The injection was made with ~500bar (plastic pressure). Probably on a manual lever one the difference is a lot bigger and maybe the injection speed can be too slow to achieve a full mold fill. In my case the mold was at ambient temperature (less than 20°C) for the first shot, the yellow pink one, and maybe 25 for the second, since the mold heat a little from the first shot. Barrel temperature 180°C, nozzle temperature 200°C.

What does post-processing the formworks after casting the concrete entail?

Do you mean cleaning the concrete off?

3:53 PM

We found that we could scrape the concrete off very easily. Where it set to the brick rather rest of the wall. HDPE is notoriously hard to adhere to.

Excellent. How many uses are you typically able to manage before the parts need recycling?

Well we haven't used the bricks that many times yet, but we're also developing ways to repair them in the field.

3:46 AM

My suspicion is that with light repairs (filling holes left by screws for instance) you'd get hundreds of uses.

3:47 AM

Especially if you paid attention to the plastic's environmental sensitivieis; ie, not leaving UV sensitive plastic in the sun.

3:47 AM

Not using solvents near it.

PP Philippines is making our third move in 5 years. We out grew the 1 car garage, then the second space we outgrew last year but was only able to find a affordable space a few weeks ago. We are still in the process of setting all our machinery up, organizing the ton of parts and materials (including the failed experiments). We will have a v4pro type extrusion and a v3 type extrusion running, plus one log splitter injection molder, two pneumatic injection molders, 1 diesel powered v3 shredder, 1 unit 5hp PP Ph granulator, dust collection system, shred plastic storage silo, and a proper street located plastic purchasing station.

4:03 AM

today we are building shelving for the materials, security gates for one of the out buildings, installing industrial wiring and outlets for the molding machinery, fixing the fencing, and installing the CCTV

500 bar ??? Are you sure you are pressing 500 bars of pressure in your mould? I have a slightly modified INJECTO (https://www.youtube.com/watch?v=M28Pbrm7wzE&ab_channel=ActionBOX) my working pressure is between 2 and 3 bars for a sandwich-type hexagone mould.

Yes. Just make some calculations. The injector is mounted on an hydraulic press (designed for the scope). Up to 280bar oil pressure. Hydraulic cylinder is 50mm Injector piston 30mm. The area ratio between them is 2,778, so 1bar oil pressure equals 2,778bar injection pressure. Usually I use an hydraulic pressure of 160~190 bar for plant pots, depending on the plastic quality and temperature. So an injection pressure varying from 445 to 530 bar. As you certainly know, there's some differences between the pressure you can apply with air and oil systems! Try to make this level of detail with a low pressure. The gate is ~1mm in diameter, on the ring, the tail is something like 0.5mm thick or less at the end!

All those seahorse keychain are made with HDPE from blow molding bottles, so the thicker kind of HDPE. Expecially the yellow one give me lots of problems in the past, here I started with a slightly heated mold (maybe 70° probably less) and I had no issue.

Very cool! Just out of curioisity, have you tried making PLA sheets? I've made a few but also I've had a few that ended up cracking and being unusable...maybe I got the temperature wrong or it was mixed with PETG.

What size? We made PLA sheets, but not many and usually small ones (up to 40cm). We only had one cracked sheet but in that case the temperature was indeed too high

Ahh I see. My sizes were 44cm x 44cm x 3mm. I have a feeling I got it too hot, but also the other issue was the pigment sticks to the steel plates a bit and can cause color contamination for other sheets. I should try this again!

All of the sheets are HDPE but we should give PLA a try, definitely melts/flows at a low temperature

one of the members of our workshop 3D prints clinostats (https://cosecloud.com/product/scispinner-max-3d-clinostat/), when they parts fail to print they go back into the shredder

They're impressively huge parts, but we had to buy an industrial shredder to rip them apart it stalled the PP design

We also intend to do more tests, we are just lacking time xD

Our first prototype is done ^^ we will present it at a small pitch competition on 11 May in Düsseldorf, Germany ^^

No, these are compression moulded. So we make a 10 gauge steel mould following (https://community.preciousplastic.com/how-to/create-a-bowl-using-a-laser-cut-mould). We're putting plastic in the mould, into the oven and heating it. Pulling it out of the oven and squishing it in a press to form then holding it until it cools a bit

our best lumber to date. HDPE bottles, from a chain of salons, haircare products. Mixed with iron oxide pigment directly in the shredder/granulator on the second pass.

Seriously good looking stuff

thanks. the trim router with the radius on the edges really gives it a nice look

today we are reprocessing all the shavings from the wood planer to make more lumber.

maaaan this looks like wood LITERALLY

Since I have to learn how to use Fusion 360 to make molds, I started with another keychain a couple of weeks ago. This is made for a friend, for his small garage, in wich I was allowed to work on my car for free for something like 15 years... He saw the first keychain I made for other friend's association, and he liked it, so I started making a simple logo for him and I made another mold. I have to add a couple of screws, since the pressure tend to open the mold a little when full. Fusion 360 is a very powerful instrument.

Two shapes, two molds. Just take your mould material you use for your planks and cut yourself the angle you need.
