Printing Carbon Fiber Filament on the Kobra 3

Printing Carbon Fiber Filament on the Kobra 3 PLA-CF and PETG-CF print stronger, stiffer, and lighter than standard materials — but they're abrasive and need specific handling. Hardware Requirements Hardened steel nozzle required — CF chews through brass nozzles in hours The Kobra 3 stock nozzle is hardened steel — you're good Do NOT use a 0.2 mm nozzle with CF — minimum 0.4 mm PLA-CF Settings PETG-CF Settings Key Differences from Standard Materials Layer adhesion is weaker — CF interrupts polymer chains. Use 4+ walls. Very low warping — fibers resist shrinkage Brittle in thin sections — design walls thicker than you would for PLA Excellent stiffness — great for structural brackets, tool holders, drone frames Matte finish — CF gives a distinctive matte black look Common Issues Not Suitable For Fine detail work — CF particles reduce resolution Anything requiring post-processing with acetone Multi-color with ACE Pro (abrasive wears hub)
