Carbon Fiber PETG
Carbon-fiber-reinforced PETG: stiffer, more dimensionally stable, with a matte finish. Needs a hardened nozzle.
Print temperatures
Nozzle 240–260 °C Bed 70–90 °C
PETG-CF takes PETG's durability and adds carbon-fiber stiffness and dimensional stability — and the fibers actually reduce the stringing that plagues plain PETG.
Like all CF filaments it's abrasive (hardened nozzle required), and the fibers boost stiffness more than ultimate strength.
Strengths & trade-offs
- Stiffer and more dimensionally stable than PETG
- Reduced stringing vs plain PETG
- Good chemical and heat resistance
- Premium matte-black look
- Lightweight
- Abrasive — hardened nozzle required
- More brittle than plain PETG
- Hygroscopic — dry before printing
- Needs a larger nozzle (≥0.4–0.6 mm)
- Pricier

Did you know
- Adding carbon fiber actually helps PETG print — the fibers cut the stringing plain PETG is notorious for.
- As with all chopped-CF filaments, the fibers chiefly increase stiffness, not impact strength.
