ASA Filament

Acrylonitrile Styrene Acrylate

A
Also known as:Acrylonitrile Styrene Acrylate
Family:ASA

Why Use ASA?

  • Excellent UV resistance (outdoors indefinitely), tough, matte surface
  • Less warping than ABS; low viscosity enables very high speed printing
  • High heat tolerance (~boiling water range)

Things to Consider

  • Still off-gasses; enclosure/ventilation recommended
  • Can still warp; needs tuning

Safety & Ventilation

  • Print ASA in a well ventilated area. Higher-temperature materials like this can release fumes and fine particles while printing. An enclosure improves print quality and helps contain fumes, but it is not a substitute for fresh air, so vent the enclosure or run an air filter and avoid an unventilated occupied room.
