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.

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?
