Protopasta 3D Printer Filament, PLA Filament 1.75mm, Composite Carbon Fiber PLA, 500g Spool
Proto-Pasta PLA-CF 500g prints on the PLA-CF profile below. PLA-CF is best suited to stiff, matte display pieces, desk and camera accessories, and light-duty brackets that never see heat. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Bambu Lab and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our carbon fiber filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Carbon fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
Based on Bambu Lab and Prusa guidance. More in our carbon fiber filament guide and nozzle types guide.
