Carbon Fiber reinforced PLA + with short chopped Carbon Fibers. It is designed to be stiff, or to resist bending. It is the stiffest material most offer and makes parts with an incredibly solid feel. When printed, this material is a dark glossy black that glitters slightly in direct light from the fine chopped fibers reflecting the light.
Carbon Fiber Reinforced PLA + does not require a heated bed and prints much like unreinforced PLA + filament. We have had good results printing at 190C-210C using a .5mm nozzle and direct-drive spring loaded pinch-roll style extrusion head. Layer adhesion is excellent and the material has low warpage.
