ASA 3D printing filament (Acrylonitrile Styrene Acrylate) is a UV and weather resistant polymer, making it the go to 3D filament for outdoor application. It's an improved version of ABS 3D filemant and it's chemical resistant, high strength and quite rigid!
ASA 3D filament has a stable interlayer adhesion and is label as producing one of the best aesthetics possible with 3D printing.
Much like ABS filament, ASA filament requires a 3D Printer's hotbed that can go in the 90-110 ºC range.
**Always put your 3D Printer filament spool back in it's bag and away from direct sunlight to maximise shelf life.
