Super Polymer Composites

CF/GF Super • Carbon/Glass Filled PEEK, PEKK, PEI, etc.

C

Carbon or glass filled versions of PEEK, PEKK, PEI, etc. Since super polymers are already so stiff, the additive mainly reduces warping and makes prints look less like solidified urine. Very few printers can feed such stiff, rough filament.
