PA-CF (Carbon Fiber Reinforced Nylon) is one of the most-used 3D printing materials. In plain terms: carbon fiber strength with stunning rigidity.
VOXFIL PA-CF blends nylon with 15% chopped carbon fiber for extreme stiffness, dimensional stability and a premium matte black finish. Parts hold tight tolerances and resist creep — the choice for drone frames, brackets and high-performance jigs.

How to print PA-CF
- Nozzle: 260 – 290 °C, hardened steel nozzle required
- Bed: 70 – 90 °C, enclosure recommended
- Speed: 30 – 60 mm/s
- Abrasive — use hardened nozzle, never brass
Best applications for PA-CF
