Carbon fiber filament increases stiffness and dimensional stability, but it is not automatically stronger in every direction. Impact toughness can fall and nozzle wear rises. Use it where stiffness and weight matter.
Benefits
- Higher stiffness.
- Lower warpage in some parts.
- Good dimensional stability.
- Useful for fixtures.
Limitations
- Abrasive to nozzles.
- Can be brittle.
- Rough surface.
- Anisotropic strength.
Printing rules
Hardened nozzle, dry material, controlled temperature and flow. Align layers with the load and test the real part.
| Requirement | CF value | Risk |
|---|---|---|
| Stiffness | High | Brittleness |
| Weight | Lower | Density |
| Dimension | Stable | Surface |
| Impact | Variable | Direction |
Common engineering mistakes
- Using brass nozzles.
- Judging by stiffness alone.
- Ignoring orientation.
- Printing wet material.
- No maintenance plan.
Buyer checklist
- Is stiffness required?
- Is impact expected?
- Is the nozzle suitable?
- Is flow calibrated?
- Was the part tested?
