Printing Proto-Pasta PLA-CF

Proto-Pasta PLA-CF in Black is PLA filled with chopped carbon fiber, and this listing is a 0.5kg spool. The fibers make parts stiffer and more dimensionally stable than plain PLA, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for PLA-CF, which usually prints a little hotter than plain PLA. 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.

Nozzle Compatibility

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.
