Before you print

2 things to know about this spool

  • Print inside an enclosure

    It cools too fast in open air and can warp or crack. A closed-in printer holds the heat around the print (chamber at least 55°C).

  • Give it plenty of fresh air

    It gives off fumes as it prints. Run it in a well-ventilated room or a filtered enclosure, not a closed bedroom.

New here? Nozzle = printing temperature in your slicer, bed = build plate. Start at the big number.
  • Nozzle is the hot-end temperature: enter it as the printing temperature in your slicer. Start at the big number; the range is the safe window to tune within.
  • Bed is the heated build plate: your slicer calls it bed temperature. It helps prints stick.
  • OFD is the Open Filament Database, the community-maintained source this spec sheet comes from.

Editorial notesUpdated 2026-05-10

Print with ventilation — ASA fumes are irritating in enclosed spaces.

Solid UV-stable option from Prusa with their usual tight diameter tolerance. Pairs well with the Prusa MK4 enclosure if you have one. Lower warping tendency than generic ASA brands in community testing. As with all ASA, run ventilation.
