There has been a bit of confusion regarding the failed 3D print and filament being shredded. Indeed both were shred and used in the final sheet. The point being that both the failed prints and the filament were PLA, hence the mixing. The process would be the exact same had we use exclusively failed prints. We hope this can still be useful to many out there 🤙
I guess all I need now is this big ass industrial press and a plastic shredder. Then I can make a big plastic sheet and put my dog on it. Very useful.
I, on the other hand, would put it on top of a nice structure and make a table out of it
The sheet did not seem to be made from recycled waste but with shredded filaments that were uniform, your process will deviate a lot with larger particles and different shapes of shredded materials. Also, for the mold release, there are a lot of powder releases available that might be cheaper and faster than spraying on silicone ones.
indeed. Very missleading.
I always love to see people focusing on recycling the plastic from failed prints, bonus points if they are from my country :D
They actually don't recycle they use PLA pellets bought separately. No recycling happening in this video.
@@antonkukoba3378yea, they do not have access to that much pla failed prints but I'd say it can work the same, i've seen people make these at a smaller scale at home so why wouldn't it work on a larger scale with less waste?
@@antonkukoba3378good proof of concept tho, teaching tech made of video of doing this on a more small consumer scale and used shredded print waste for it. And it looked great like this
you started out with shredded prints and supports, but then you used shreddeds filament. i wanted to see the process with shredded prints though. :(
Sorry if this caused a bit of confusion. The process is pretty much the same, doesn't really matter. You just have to shred the failed prints. Once you have the shredded plastic the remaining of the process is the same.
lol
meaning you have to have an access to a machine that shreds plastic and costs a lot of money...
@@CraftySvenA blender works.
That's right @@CraftySventhis cost is especially stark when compared to 3d printer farms, which grow in trees wholly formed and are commonly given out in place of change when buying groceries.
Right?
Great point in connecting two passionate communities that are currently on the opposite sides of recycling. We should definitely promote filament recycling and collection centers as most of 3D printer users would not have the sheet presses, but have good quality raw materials they paid premium for.
Would be a pretty solid business model, buy the scrap by weight and make sheets to resell🤷♂️
Bellissimo lavoro ragazzi, da appassionato di making questi sono contenuti davvero interessanti (e anche impacchettati bene!). Keep it up
GRAZIEEEEE ♥️
Thank for your sharing. I love this project
Instead of using silicone release, maybe look to bakers who use parchment paper. It can take the heat and isn't very expensive. Can possibly used multiple times as well.
I have used parchment paper in my small scale experiments in a toaster oven, and it works very well
@@flyingpurplebovine what temperature would you recommend and how long does it usually take?
@@rondelapena6024 I had it at about 400F (200C) for about 20 minutes, and that made pliable kind of like silly putty. I used silicone oven mitts to mold it and stretch it, and I could put it in a manual mold. The final result still had some small air gaps, but it was a very successful proof of concept
Parchment Paper will degrade over a certain amount of time. There are textiles that can widstand it ( haven't researched what they are called ). But for repetitive usage silicone can widstand the heat and if could be reformed if done by in a mono material fashion.
Where I worked 30 years of my life, we ground up our pet and mixed it back in with virgin raw materials for reuse. WE had very little waste. I seems there might be a market for grinding up separated waste by color and type and extruding it back into 1.75 mm rolls.
You might be able to use these as tiles to walk. I don't know what the hardness is or if it's fragile. But small tiles might be good for a workshop type setting.
I'll certainly be looking into tiling my workshop with that.
Oh wow! I was looking at trying to figure out how I was going to do this with all of our plastic print waste we generate in my shop. Great video!
Aren't there machines to make new filament from leftovers? Seems much more efficient than wasting energy on making a huge PLA sheet
@@BaldyMacbeardif you have some 3000kg it might be worth making filament 😂
was tat panel made of shredded Filament? the pellets shown were strangely cylindrical
3:00 and 4:32 shred filament has different shapes. I'm confusing. 4:32 shred filament is not pellet, but broken filament.
3:00 is support material (PLA) while 4:32 is indeed shredded filament (also PLA).
05:08 prevent bubbles in the shit 😄
I may have another comment towards the end, but I must point out that at around 2:09 your support settings are WAY too aggressive. You can easily cut your support angle down to like 45-65 and shave off around 30% of your support material by no supporting such shallow angles.
Especially with quality machines like Pursas you can get away with pretty heavy overhangs. I would suggest running one of the overhang tests to see where it starts to mess up, then adjust your settings 5 degrees below that.
I wonder how the process changed the chemo-mechanical properties of PLa ? Did they heat it over the crystallization temperature? Is crystallized PLa UV resistant after re-crystallization at higher temperatures into sheet? Also, people misinterpreted the plastic used, the smaller fraction shredded material should have sieved down below and bigger fragments stay at the top, those were clearly NOT pellets, pellets are way smaller.
looked like what they poured into the mold was cut up off spool pla, almost like there using moastly end spool lengths, rather then failed or excess prints... no other way to provide consistency of speckling in the end product....
il tuo inglese è perfetto, sei un grande continua così
Cool sheet, bro!
Ok, now that we have big plastic plates...
What to do with them?
What are they used for?
here you can see some good examples th-cam.com/video/phcUDITNrBE/w-d-xo.html
At 1:06 I looked away and I thought he said “the best recycled shit”😂
So do to alot of ommissions, the demonstration was using "spool diameter plastic" cut to pellet lengths, at 7:38 you can see a giant bag of white pla almost like end spool plastic. from a commercial print shop as they are likely forgoing the remainder of the spool instead of pause print change spool in there setups, so the end spool waste is likely to be the primary input to this technique and how they get that look to the final sheets....
You can learn more about the "giant bag of white pla" on this video th-cam.com/video/lIWeHHDiePY/w-d-xo.html
Amazing.
Love the process, but what is the end product used for? I would have thought PLA's glass transition temperature would be too low to use it in most applications...
We send our PLA and PETG "waste" to a local recycler that makes rFilament for us. For everything else we're looking forward to establish a local space to recycle plastics.
Very helpful to regular folks
I don't think he got your sarcasm because he liked your comment lol
@@Vitoria-ug9cc I know lol :)
Perfect for bench tops!
Hey, so I've been trying things out in my garage along these lines. One of the issues though is that the pla after I am done is very brittle and when it breaks it shoots bits of it all over the place. That may be down to temperature (I use a higher temp than you did) and material purity (my pla often has polyester in it as they use it for shiny colours) Id be interested in knowing what types of end products you intend to make with those sheets.
Edit: oh also can you run pla through the injection mold device?
PLA becomes stiff if kept at high temps for a long time, I think you're overcooking the outside and undercooking the inside from that description so too much heat for too little time. Also, filament could be getting moist after being printed and that might make it full of steam pockets which would make it brittle and worsen the heat conduction throughout the material, but with the little information I have I wouldn't be surprised if I was completely wrong.
@agasa_workshop well that sounds valid. Ill try with lower temps to see if that reduces the hardness.
Hmm, I'd also try my hardest to keep PETG or similar polyesters separate from PLAs. I've heard they don't alloy together well, and just from my experience with the material purged from the nozzle when switching between the two, mixtures of the two seem to be more brittle and fragile than PLA alone?
If that's what you meant at all, anyway, if you just meant the additives in 'silk' or 'impact-modified/plus' PLAs, I don't really have experience with those. As far as I know, they should be making the PLA softer, not harder. Strange.
@05Matz Yeah, so what I meant was I print with a fair amount of silk pla. The one particular brand I looked at the additive components and polyester was the largest portion. I kinda assumed that was generally what the silk addative was. Looking into it a bit that seems to not always (or even usually) be the case.
Yeah you do injection molding with pla, there are videos for it on TH-cam
Would be nice if there was a more cost-effective solution for shredding. Or some recycling places who would accept 3d print material for this purpose. In the US, there aren't many that I can find.
here you can find some community.preciousplastic.com/map
@@Precious_Plastic The map is grand! Alas, being in Edmonton, Alberta, it looks like the closest collection site is almost 2,000 km away, which I think speaks to @legacyofbob 's concern. There's a place that's *using* recylced plastic much closer - looks like about 20 km, though they don't seem to want to share their address with the world - but they don't seem to be collecting waste plastic from random people. So, definitely not a lot of recyling infrastructure on the western side of North America.
Oh hey, I'm in a small town near Edmonton, dreaming of the day I could reclaim my 3D printing waste, either as filament or in some other useful form, or really anything to keep it out of the landfill or worse. @@davydatwood3158
It's honestly deeply frustrating, having learned so much about plastics, recognizing all the sources of useful high-quality plastics we accumulate and being unable to stop them entering the waste stream. I keep having to stop myself from hoarding plastic waste just because it's clean and of known composition, and the fact that I don't have a waste recycling plan lined up has put a serious damper on my 3D printing hobby, because it feels so bad to throw away things you know have value. I really wish there were a hackerspace or something I could go to with recycling equipment, even if I had to travel as far as Edmonton I might make the trip every year or so with a van full of stuff to be recycled.
Our local recycling service doesn't even take most _actually commercially recyclable_ sources of plastic. They want only the highest-density types of items from a few polymers, even turning up their noses at thin vacuformed pieces (such as clamshell-style containers) of the plastics they DO want, presumably because the profit per labour-hour is smaller.
So...... What do you do with the big sheet of plastic? Seems to be just waste in another form unless you can use the sheet some way.
I'm assuming this can be shaped using different tools like saws, drills and other carpentry tools. I'm not sure there are a lot of uses for a 1" x 1-meter square.
It's called 'stock'. It's the basic starting point of a lot of products.
I don't know what use a plate with that kind of thickness is, but I don't have experience working with plastics and I'm fairly confident there's uses for 1x1 meter squares like this. Insulating floor tiles come to my mind.
You can also cut it using a laser cutter
Hi, I'm a newbie to 3D printing. Can the waist materiel not be smelted and then be extruded to make more filament?
It teeeechnically can be done. The problem is the number of technicalities involved. Hence, currently, it isn't easily available to all makers.
Some reasons: plastics are polymers, meaning long molecules consisting of smaller molecules (monomers), kinda like chains. Generally, every time you heat and melt plastics, those chains break more and more, and your plastic degrades. Becomes more brittle, loses its valuable properties, etc. There are whole industries dedicated to solving and sidestepping this issue, so it's not an easy thing to solve. Another reason: during the heating/melting process of a lot of plastics, you get toxic fumes. So it's not safe to just tell anyone to do it, especially at home.
These are just some of the problems.
Great potential here if think, but what do you do with the sheets of PLA? Doesn’t it have a melting point too low for many applications?
Resulting sheets can be used in multiple applications from interior to product design, no issues with temperature..
Depends on the application I guess. The low melting point might make them easy to weld, now that I think of it, meaning that if you get access to _enough_ of it you might use it for really big constructions welded together from multiple pieces. (sheds, tables, etc.?)
Your local climate would determine where it's usable, though. Generally, temperatures dangerously high for humans would also cause PLA to lose its strength and slump, so you wouldn't want to use it in anything like a car that would be left in the hot sun producing a 'greenhouse' effect with its windows. If you're in a cooler climate though, it should have little trouble with the temperatures outside, as long as it's not directly under the noonday sun or 'trapped' with sun-heated air behind a window? I'd also consider the possible UV vulnerability before using it outdoors, though. I forget if PLA is UV sensitive or not. Also, PLA, being... kinda-sorta-semi-biodegradable, is often not recommended for use underground, as bugs or microbes in the soil might nibble on it and weaken it over time like they would untreated wood. I don't know how realistic this scenario is though, as the 'biodegradability' of PLA is typically seriously overstated -- it will be assimilated and disposed of as waste by animal tissue, meaning that once it ends up as microplastics it at least goes away after the first fish or other critter swallows it, but apparently getting microbes to actually decay it requires pretty specific conditions.
In general, I'd think that furniture, project boxes, etc. might be a good use for PLA sheets. I want to see if they can laser cut it! If it can be planed down to a precise thickness and laser cut, then that's a method to make dimensionally accurate parts out of recycled plastic!
@@05Matzyeah teaching tech made a video using this method on a smaller scale and laser cut the pieces. It definitely has potential for all sorts of things
I'd look at using smaller molds in the sheet to make "tiles", those would sell like hotcakes.
Or other plastic surplus from manufacturing. Fyi. 😊😊
Hej, thanks for the video and stay safe ✌️.
Can you repeat this same process with crushed glass?
nice work :)
Good old ranocchia playing the algo ♥️
Could you use petg or abs mixed in too?
Nop, ideally different types of plastic are never mixed as that ends their life cycle
Those pellet looking "3D print shreds" are actually pellets, I clicked the video hoping to see the proces of actually cleaning(I assumed there would be cleaning and sorting or something like that) and using the 3D printing waste :(
Grandi 💪🏻
¿Can you explain what kind of plastics is possible to mix to make sheets?
You can use PLA, ABS, sometimes PETG in the sheet but make sure to never mix them together!
@@Precious_Plasticmy question was about mixing…😅 ¿what plastics can we mix?
@@markpupetxideally you wouldn't mix anything if possible because some don't even bond together, others may degrade at different rates over time. I would recommend if you want to mix, at least separate by the base polymer. PETG and PLA only will mechanically join for example. ABS and ASA may bond but don't share the same properties, so depending on if you want to use the finished plastic sheet outdoors, the ABS will degrade faster in UV light. You can better control the properties of the sheet when it is all the same.
With that being said, ABS, ASA, PETG, they will probably melt and mechanically link if you don't care about the physical properties
@@Precious_Plastic "tough PLA" was sometimes PLA+ABS
It would be really neat to have a process to be able to test which plastics are which in case they got accidentally mixed together. Otherwise it's really hard to trust this process.
Definitely. Appropriate segregation processes need to be be in place to make sure materials are not mixed. This of course while we develop a plastic scanner :)
You need lad equipment and tools. We tested all of our pet before use for UV durability, tensile strength and density.
There's a tester for that. Identifies various plastics.
Hey it's Mario and LUIIIIGIIII
Cool🎉
3:15 made me giggle
what does this sheet do? how is this valuable? what would you use this for? i don't get it
Sheets are the starting point for further circular products, they're usually used in interior design, furniture, architecture and more! you can see some examples here th-cam.com/video/phcUDITNrBE/w-d-xo.htmlsi=qHZuRKJhH5y4zNdz
Please remove the protective foil from the electrical box under the sheet press, my ocd can't handle this!
I hope this gets more views. such quality
Amazing shiit.
💩💩💩
I don't get it, you made a giant Square, what are you supposed to do with it?
Furniture, interior design, CNC, products, the sky is the limit 🙃
Hey, I contacted you recently, gonna bring some stuff soon over to you
Do you sell these sheets?
*shits
What is the cost of electricity? Your bills must be huge? Otherwise great result!
Yep it is non-negligible
This had a swap at around @3:00 between shredded recycled filament and what are clearly uniform pellets ... for the rest of the process ... so it feels slightly disingenuous to then be talking in terms of recycled plastic when the output we saw made did not use the recycled input you suggested.
What is the use of these giant plastic tiles? As they are made from PLA, they will warp and deform if used in a slightly warmer environment and if you use them anywhere exposed to the elements, they will degrade to nothing within a few years.
Those sheets can be used in a variety of applications, from interior design to furniture. We haven't had issues with temperature so far, maybe because of the thickness?
"... they will degrade to nothing within a few years." if only that was true, unfortunately we still need industrial facilities to properly recycle PLA.
Can we send you bags of waste for you to use and make something with?
It's like making pizza! Lol
Better 🤪
have this playing in the background and every few minutes i get reminded of exactly how immature i truly am.
Why 🫣 ?
@@Precious_Plasticthey are immature because they thought the pronunciation of sheet is funny
Dude acted like he was using shredded failed prints and supports and just used plastic pellets...
We used failed 3D prints and discarded filament, no pellets :)
Eitherways the goal is to use 3D print waste material to make something precious once again if is in the form of failed prints or discarded filament doesn't matter, we aim this video to inform people they can use 3D print waste streams in their Precious Plastic machines
The sheet does look a lot like uniform pellets. You showed the prints being shredded, and they clearly weren't the same.
@@bestpony12It looks like a bunch of shredded up filament that hadn't been printed with.
What do you do with these plates? Wouldnt it be better to recycle the PLA into new Pla Filament?
Ahahahaha they put the pellets in the mold, not the shreded PLA. Just pause and see it yourself at 4:32 or 4:42. Such a bullshit recycling. These pellets are the source for the filament, and they just use ot for the molding, the same way ABS is used for injection molding.
They said they shredded PLA filament wire
That plate was made using original pellets, not failed prints. Not very consistent...
This is no true, no pellets were used. Only shredded failed 3D print, support material and waste filament. Sorry for any confusion in the video.

Well that's a misleading title. "What to do with all the 3d printed plastic waste?" Nothing I can get from this video, for sure, because I don't have a giant plastic press at home. The answer to that question is "take it to a recycling plant" and where to find one, which was not covered in the video. Additionally, your sheet wasn't even made out of 3d print waste. Change your title.
How is a sheet of plastic useful? Sure you can make one with waste plastic, but why bother if you're gonna just make a square of plastic...
You could make a whole store with them 😍 th-cam.com/video/7q_a4JaSVnA/w-d-xo.html&t
shit or sheet? xD
ok.... don't crucify me please, but since you and your team are not able to pronounce the word "sheet" correctly, and you keep saying "shit" all the time... I highly recommend that you try using another word like "laminate" or "film" or "plate". I know it is frustrating, but this mispronunciation is somewhat important and it does create a distraction when you keep saying things like "now look at this beautiful SHIT that came out of the press". sorry... but it is just how the English language works.
ahahah thanks for pointing this out. Downsides of non-native speakers :) Indeed we ought to use alternative words. Even though is kinda funny 😂
@@Precious_Plastic it is kinda funny indeed... but after 10 minutes it gets old and a little distracting. it is not a big deal though.... hahah. I am brasilian and once I said to a girl "I love your teeth".... but I pronounced tits!! haha
