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 compared to ABS. Its brilliant thermal stability, great filament flowing behavior, zero-warping and flawless interlayer adhesion allows you to 3D print objects with an almost injection-molded precision - due to these special characteristics ASA is being used successfully in the building/construction, automotive and recreation industries
The 3D4MAKERS ASA Filament contains unique properties because the material has an extremely constant diameter and roundness. On top of that the ASA filament does not come into contact with water during the production process and is directly packaged in a vacuum packaging. These properties make the 3D4MAKERS ASA Filament particularly suitable for FDM and FFF 3D printers. The material has an excellent adhesion between layers which results in great improvement of the impact resistance, strength, durability and the printing process.
