Raise3D Industrial PPA CF Filament (1.75mm): Black - 1kgRaise3D Industrial PPA CF Filament is a carbon fiber reinforced composite filament material based on PPA (polyphthalamide or high performance high temperature Nylon). Thanks to its high performance Nylon matrix, this composite filament exhibits superior mechanical and thermal properties compared to other Nylon filaments. With well controlled dispersion and length distribution of chopped carbon fibers (15 wt.%), PPA CF offers lower density, reduced
