Product Details
- 8% Recycled Carbon Fiber PETG: Fiberon PETG-rCF08 combines PETG with 8 wt% recycled carbon fiber for improved rigidity and strength compared with standard PETG. A practical choice for prototypes, brackets, housings, jigs and fixtures.
- Clean Matte Surface: The carbon fiber texture creates a professional matte finish that helps reduce the visibility of layer lines. Ideal for functional parts that also require a clean, refined appearance.
- Low-Warp, Reliable Printing: Designed to provide stable dimensions, good layer adhesion and low warping without requiring a heated chamber. It offers an accessible way to print carbon fiber composite parts on compatible desktop 3D printers.
- Recommended Print Settings: Use a 240–270°C nozzle, 60–70°C build plate and 0–50% cooling fan. Printing speeds up to 300 mm/s may be achieved after calibration. A hardened or wear-resistant nozzle is required because carbon fiber is abrasive.
- Drying and Application Guidance: If the filament has absorbed moisture, dry it at 65°C for 3 hours and store it in a sealed, dry environment. Annealing is not required. With an HDT of 68.6°C at 0.45 MPa, it is intended for functional parts used at moderate temperatures.

Printing Polymaker PETG-CF
Polymaker PETG-CF in Matte Black is PETG filled with chopped carbon fiber, and this listing is a 0.5kg 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.
