Proto Plast Carbon fiber FIlament, Made in The USA.
Carbon Fiber Reinforced PLA filament provides fabulous structural strength and layer adhesion with very low warpage. Due to the carbon fiber contained in the filament, it has increased rigidity, therefore increased structural support built right in. Carbon Fiber filament is perfect for printing items that do not bend, such as: frames, supports, propellers, and tools - drone builders and RC Hobbyists love this stuff, and it is made in the USA! The carbon fiber in the filament is specifically designed to be small enough to fit through the nozzles, but long enough to provide the extra rigidity that makes this reinforced PLA so special.
