What to do with all that 3D printing WASTE? 

I, on the other hand, would put it on top of a nice structure and make a table out of it

indeed. Very missleading.

Would be a pretty solid business model, buy the scrap by weight and make sheets to resell🤷‍♂️

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

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?

GRAZIEEEEE ♥️

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.

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 😂

3:00 is support material (PLA) while 4:32 is indeed shredded filament (also PLA).

I don't think he got your sarcasm because he liked your comment lol

@@Vitoria-ug9cc I know lol :)

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....

here you can see some good examples ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-phcUDITNrBE.html

You can learn more about the "giant bag of white pla" on this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lIWeHHDiePY.html

Good old ranocchia playing the algo ♥️

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 RU-vid

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.

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

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

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.

Nop, ideally different types of plastic are never mixed as that ends their life cycle

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

💩💩💩

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.

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-phcUDITNrBE.htmlsi=qHZuRKJhH5y4zNdz

Furniture, interior design, CNC, products, the sky is the limit 🙃

*shits

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.

Yep it is non-negligible

Better 🤪

They said they shredded PLA filament wire

Why 🫣 ?

​@@Precious_Plasticthey are immature because they thought the pronunciation of sheet is funny

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?

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.

Semi industrial.. all you need to know to build them is here preciousplastic.com/solutions/machines/pro.html

You could make a whole store with them 😍 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7q_a4JaSVnA.html&t

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
