Recycle Plastic Into 3D Printer Filament at Home

Hello dear Reprap community !

Long time reader, first time poster.

Few years ago I started experimenting with converting plastic scrap into usable 3D printer filament at home and today, I'm publishing a guide about that.

Cheap and home scaled focused. The process consists in sorting and cleaning plastic pieces taken from defective household appliances, grinding them to small granules, and feed those granules to a home made small extrusion line. After a quick post-processing step, the output filament can be used by a 3D printer to print new objects.

This is far away from being perfect but maybe some useful infos could be found inside the guide for those who are in the same kind of research.

Everything inside is open source.

I'm happy to share thought about it,
Have a good day,

3D printing was supposed to lead to less waste, yet how I think it leads to more, with the number of test prints I end up making on my way to a successful design.

The effort you are putting into creating 3D printer filament from waste plastic is inspiring.

Maybe a plastic shredder from the Precious Plastics community's designs would be useful to you.

Yup !

Precious plastic shredder would be very usefull ideed ! But it is a bit over-scaled for my approach.

Cheers
