Overview
PETG base with chopped carbon fiber reinforcement. Dramatically increases stiffness and reduces weight vs unfilled PETG while retaining PETG chemical resistance and minimal warping. Matte black with visible fiber texture. Must use hardened nozzle.

Pros
- Much stiffer than unfilled PETG
- Low warping like PETG
- Good chemical resistance
- Matte carbon appearance
- Better dimensional stability
- High strength-to-weight
Cons
- Very abrasive — destroys brass nozzles rapidly
- More brittle vs unfilled PETG
- Higher cost
- Mostly black only
- Weaker in Z-axis vs XY
Best For
- Structural brackets|Drone frames|Robotics|RC car parts|Engineering prototypes
Avoid For
- Standard brass nozzles|Parts needing flex|Appearance-critical light-colored parts
Storage
Dry storage essential. Use hardened steel nozzle. Print 10-15% slower than unfilled PETG.
