Intermediate

Acrylonitrile Styrene Acrylate

ASA is ABS's weather-resistant cousin. It offers similar mechanical properties but with significantly better UV and outdoor resistance. If you are printing anything that will live outside — garden tools, outdoor fixtures, automotive trim — ASA is the correct choice.
