Re: three extruder , three diffrent filaments

Hi all,
I'm starting a thesis in plastics recycling and cannot find a reasonable priced extruder for plastic recyclates. PLA & ABS only extruders are of no interest, HDPE is most important, PET second with others (PP, PS etc as a bonus). Any help that sends me in a  particular direction would be most appreciated! In terms of selfbuild, I am already finding it impossible to get anyone to machine a hex bar for my shredder kit - so unfortunately it needs to be completed machine or very near to it...........
Cheers (fingers crossed),
Cara

Re: three extruder , three diffrent filaments

carakeane,

I'd be interested in running HDPE, too. Even so, the experience of people who deal in HDPE filament might be instructive.

"Please note: HDPE is a very challenging material to 3D print with. Although we have managed to get some successful prints, we have by no means perfected a reliable way to print with this material. We welcome any feedback related to printing with HDPE." https://filaments.ca/products/hdpe-fila … 2590589320

I wish you the best of luck and if you're successful, you could also become rich. Keep a patent lawyer on speed dial!
