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.
  • Enclosure recommended — Shrinks enough while cooling that draughts cause warping and split layers. An enclosure, or simply a still room, makes the difference.

True of ASA-CF generally. Follow Spectrum’s own guidance for this spool.
