    You should re-extrude the recycled filament which is bad, by chopping it up with a simple machine. The output should look like the masterbatch, and should function basically like the pellets, which should give you similar extrusions like the new ones.

It is a super interesting process but you need a lot and I mean a lot of knowledge about plastics and other stuff because you've got a lot of different parameters and factors that come into play.

We had the additional issue of pressurizing the draw to maintain the hollow tube aspect ratio. Obviously the temperatures were much higher, and at the time this was all analog. Also obviously the oven was much bigger and more expensive.

    Hope you try to make pallets from the shredded material by cutting up the inconsistent filament and then send it back thru for your final filament. I bet you could use an extruder to push the stage 1 filament into a rotating cutting wheel that kicks out pallets. Might not even need drying plus the first few meters of wasted plastic could be recycled almost instantly.

      I feel like the demand isn't there, much like DIY inkjet cartridge reloader machines or diy paper producers/recyclers aren't a thing. It's waaaayyyy easier to just purchase filament than to go through the hassle of making your own. I mean, most people only print PLA (honestly, 95%+ of my printing is done in PLA), and when I can find PLA for $10-$12 a roll, why would I waste my time on one of these? I mean, at that price, just tossing failed prints and support material makes sense, and with PLA being a corn based product, it decomposes quite quickly, so it doesn have a huge environmental impact.
      Now, with that being said, despite the fact that PLA can be found super cheap, I still save all my failed prints and support material and all, so I have boxes waiting for the price of these extruder machines to reach a point where I can afford one. No really to make my own plastic, but because it's just another aspect to the hobby.

      You would need to build a whole extension like with python for that. In G-code support material is the same as normal print. It just differs in speed/amount of material.

    The documentation says that it can make weaker filament if it’s not completely dry. I just bought 1700lbs of nature works PLA, and it just arrived 2 days ago. I’m a little nervous to open it all up before I know what I’m doing.

    Two tricks you could try out for the next video came to my mind:
    1. To eleviate the issue of shredded material being moved inhomogenously by the screw, first make your own pellets out of old prints. Use them to then extrude the "final" filament for more consistency.
    2. Instead of trying to make filament purely from shredded prints, you could try to add a certain (weight) percentage to virgin pellets, basically stretching the whole mixture like cocain and baking powder ;). No but jokes aside, this would offer an opportunity to reuse at least some old material, although I bet colours for example would be a bit off compared to only using virgin pellets and dye.

    In my opinion the best and biggest break through in 3D Printing would be reliable and affordable 3D Printers that you only feed directly with pellets and where the process of making spools would be skipped. This way even the environmental part of 3D printing would be much better. No more spools, no more throwing away near empty spool that don't have enough Filament for you parts and much better netto weight in shipping the pellets and ideally of course even allowing using old shredded parts.
    Really hope that this will become a thing in the next ~5 years or so.

    • @DrakeOola
      @DrakeOola Před 2 lety

      never gonna happen. It takes extreme precision even compared to a 3d printer just to extrude pellets into filament. Theses 5,000 dollar machines can barely do it with evenly sized pellets and they use an optical feedback system to precisely measure the diameter. Never gonna fit something like that into a cheap 200-2000 dollar printer. Hard enough to get it coming out at an even rate let alone starting and stopping on a whim like a regular 3d print. The stringing you'd get would be impossible to stop and like he said, heating the material for too long degrades it. Your plastic will be even more brittle than glass by the time it gets extruded if it's not turned into dust first...' Just not physically possible to melt a small volume of plastic and have it extrude evenly while also being able to prevent over extrusion during air paths. Plastic is just not the material you'd use for a pellet extruder, you'd need something exotic that doesn't degrade with heat.
      Liquids would be a million times easier to work with, perhaps some kind of solvent to dissolve the plastics with a secondary solvent that instantly hardens it. a cross between fdm and resin printers but we'd need to learn a lot more about material science before something like that is possible, some kind of material that can be turned from liquid to solid and back to liquid on a whim and not degrade from melting like heating plastic. Plastic is just too hard to recycle and too nuanced, even with manufacturers stamping the material type on bottles it's still not economical. No way we'll get that for 3D printing, not when everything is decentralized and there are millions of filament producers that use their own custom blend of who knows what type of additives. The parts you'd typically recycle being small miniatures from millions of users who each have multiple different spools from multiple different companies. You'll break the bank just trying to sort through all that and have sub-par filament that's been reheated too much and it'll ruin so many prints if even a tiny fleck of abs or any different material slips in with your plastic. Just no market where anyone would pay for sub-par recycled material at 2x or even the same cost of a brand new, hinder free spool.
      All the companies that try inevitably go bankrupt. We shouldn't be wasting money trying to make some magical recycling device, it's better spent trying to move away from plastic into something more environmentally friendly or at least easier to recycle. Not a matter of technology to make it economically viable to recycle, it's up to improvements to material science.

    Also, see if you can get your hands on MIM pellets for powder metallurgy.
