Let's find out, which filament type is the most wear resistant (in friction with the metal). Tested material types: PLA, PETG, ABS, ASA, PC (PolyCarbonate), Nylon and TPU. Effect of the carbon fibres to the wearing is also tested.
Hopefully, there will be a scientific article, the link will be included here.
