Printing this material

  • Abrasive — Contains fibre, mineral or metal filler that wears brass nozzles quickly. A hardened or ruby nozzle lasts; a stock brass one may not survive a spool.
  • Keep dry — Absorbs moisture from the air, which prints as stringing, popping and weak layers. Filament that has sat out usually needs drying before use.

True of PETG-CF generally. Follow Francofil’s own guidance for this spool.
