Printing Recommendations
Carbon Fiber Filament Printing Guide
Carbon fiber reinforced filament requires appropriate printing settings to achieve consistent results.
PLA-CF
Recommended printing temperature:
200–220°C
Recommended build plate temperature:
Around 80°C
PETG-CF
Recommended printing temperature:
240–250°C
Recommended heated bed temperature:
50–70°C
Recommended layer height:
0.1–0.2 mm
Recommended printing speed:
50–100 mm/s
Nozzle Recommendation
Use a Wear-Resistant Nozzle
Carbon fiber reinforced filament contains abrasive reinforcement particles. For extended printing, we recommend using a hardened steel or other wear-resistant nozzle rather than a standard brass nozzle.
This helps reduce nozzle wear and maintain consistent extrusion over long printing cycles.
Recommended Setup
Carbon Fiber Filament → Wear-Resistant Nozzle → Stable Extrusion → Consistent Parts
Drying & Storage
Keep Your Filament Dry
Proper filament storage is important for consistent 3D printing performance.
For best results:
- Store filament in a dry environment.
- Keep the spool sealed when not in use.
- Use a filament dryer when necessary.
- Avoid prolonged exposure to high humidity.
- Allow the material to reach the recommended drying condition before demanding prints.
For the PETG-CF reference material, the listed drying temperature is:
70°C
