ASA filament (Acrylonitrile Styrene Acrylate) is a great filament to use when your 3D printed part will be exposed to the elements. ASA is UV and weather-resistant, so it will not fade and crack as quickly as ABS when used outdoors. ASA filament is quickly becoming a popular alternative to ABS. While ASA can be printed on an open printer, an enclosure is recommended for best results.
