Carbon Fiber PETG

Intermediate

Carbon Fiber Reinforced PETG

PETG reinforced with short carbon fiber strands for significantly increased stiffness and a professional matte black finish. Easier to print than carbon fiber nylon while offering excellent rigidity. A hardened steel nozzle is mandatory.

Nozzle Temp230–260°C
Bed Temp70–85°C
Print Speed30–50 mm/s

Printing Tips

  • A hardened steel nozzle (0.5mm+) is mandatory — carbon fibers destroy brass nozzles in a single print.
  • Dry at 65°C for 8 hours. CF-PETG absorbs moisture faster than plain PETG due to the fiber wicking effect.
  • Keep fan at 30-50% — enough to handle overhangs without causing layer delamination.
  • CF composites are stiffer but more brittle. Design parts with radii instead of sharp corners to prevent cracking.
  • Use 3-4 walls minimum. Carbon fiber adds stiffness but wall count determines actual part strength.
