ASA vs ABS Filament ASA was created in the 70s by the chemical giant BASF, as an alternative to ABS- ASA refers to Acrylonitrile Styrene Acrylate. The molecular structure of ASA is very similar to ABS but instead of the butadiene rubber that acts as an impact modifier in ABS, ASA uses acrylate rubber embedded in a styrene-acrylonitrile matrix. The absence of a double bond in acrylate rubber gives ASA about ten times greater resistance against weathering and UV radiation comp
