Features of material
The ASA (acrylonitrile styrene acrylate) filament is a thermoplastic terpolymer material similar to ABS. The difference between these two materials at the structural level is that ASA uses an acrylic elastomer and ABS a butadiene elastomer. ASA is known to be stronger than ABS to the impacts even after being exposed to long periods of time in the open air, rain, cold and salt water.
ASA contains Styrene, which is emitted during melting in the form of fine particles, which can be dangerous for people with respiratory disorders and whose effects on humans are little known. As a precaution, we recommend you to use careened and filtered 3D printers in order to print in ABS, in dedicated empty spaces or spacious and ventilated place. Otherwise, please consider using the PLA filament, which does not present any known danger for the man until this day.
