Carbon and glass fiber filament require a nozzle that tolerates abrasion and matches the required detail and flow. A larger nozzle reduces clogging risk but lowers fine-detail resolution.
Choose by function
- Detail: smaller diameter.
- Speed: larger diameter.
- Abrasion: hardened material.
- Flow: match heater capacity.
Process
Dry the filament, calibrate flow and avoid excessively high temperature. Inspect nozzle diameter as cumulative abrasive material increases.
Validate
- Line width.
- Small features.
- Nozzle wear.
| Requirement | Nozzle direction | Check |
|---|---|---|
| Fine detail | 0.4 mm hardened | Line quality |
| Production | 0.6–0.8 mm hardened | Flow |
| High abrasion | Carbide/steel | Wear |
| Low use | Hardened steel | Cost |
Common engineering mistakes
- Brass with abrasive material.
- Oversized nozzle for detail.
- No wear record.
- Wet filament.
- No flow calibration.
Buyer checklist
- Is detail required?
- Is material abrasive?
- Is nozzle suitable?
- Is flow calibrated?
- Is wear measured?
