Printing IEMAI PETG-CF

IEMAI PETG-CF in Black is PETG filled with chopped carbon fiber, and this listing is a 4kg spool. The fibers make parts stiffer and more dimensionally stable than plain PETG, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for PETG-CF, which usually prints a little hotter than plain PETG. PETG-CF is best suited to stiff functional parts such as jigs, fixtures and brackets that need PETG's chemical resistance. 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, Prusament 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.

Based on Bambu Lab and Prusa guidance. More in our carbon fiber filament guide and nozzle types guide.
