Does anyone here have experience with this? I’m on the verge of buying the Artme3D extruder kit as it seems to be complete with extruder and spooler. Alternatives like FelFil Evo will sell you the spooler for the same price as the extruder which in my opinion is a scam for something that isn’t that complicated.
The next challenge is filament degradation. Ideally you add some virgin plastic pellets to recycled plastic chunks so that there is enough plasticizer still left in there. Could you just add the plasticizer yourself? It commonly is glycerol or PEG which are pretty common and easily attainable chemicals. Does anyone here have experience with mixing additives yourself?
Filament extrusion is a difficult thing.
You need to keep in mind all sorts of things just to be able to get a consistent width.
Things like:
Plastic material type (some can only be recycled so many times)
A single spec of dust can clog your nozzle
combined multiple materials will give inconsistencies
if the plastic isn’t ultra mega dry, the water will form bubbles because of steam
Creating homemade filament is not for the ones that get frustrated easily, they are far away from the quality and user friendliness that modern 3D printers have. But it is a nice little project to keep you busy.
