Carbon-Fiber Filament Printing Guide

Document the failure and confirm that it matches this guide: Filled filament clogs, wears the nozzle, or produces weak matte surfaces.

Return extreme overrides to a known printer, nozzle, material, and slicer profile so the diagnosis starts from a stable baseline.

Check standard brass nozzle wear. Use a hardened nozzle.

Check nozzle diameter too small. Choose suitable diameter.

Inspect moisture. Dry for the base polymer.

Rule out retraction excessive. Use moderate retraction.

Change only the single setting or hardware condition supported by the evidence, then run a small test that reproduces the original failure.

Compare the test against the target condition, record the successful value, and save it in a printer/material profile before repeating the full print.
