ASA

Intermediate

Acrylonitrile Styrene Acrylate

The best filament for outdoor use. ASA has 10x better UV resistance than ABS — printed parts will not yellow, crack, or become brittle in direct sunlight. Similar mechanical properties to ABS but with dramatically superior weather resistance.

Nozzle Temp240–260°C
Bed Temp90–110°C
Print Speed40–60 mm/s

Printing Tips

  • Treat ASA exactly like ABS: enclosed printer, minimal fan, ABS slurry on the bed.
  • ASA strings more than ABS — use 6-7mm retraction (Bowden) or 1.5-2mm (direct drive) at 45 mm/s.
  • Print at 250°C for the best balance between layer adhesion and surface quality.
  • ASA can also be acetone-smoothed, but it takes 30-50% longer than ABS to dissolve.
  • For outdoor parts, use 4+ walls and 30%+ infill — UV doesn't degrade ASA but rain pooling in infill gaps can.
