ASA refers to Acrylonitrile Styrene Acrylate. It’s a thermoplastic filament material used in 3D printing and enjoys numerous qualities that make it ideal for engineering and outdoor use.

As an improved version of the more popular and widely used ABS filament, ASA provides users with many benefits of ABS minus some significant drawbacks.

ASA, like its cousin the ABS, proves a little difficult to print. The printing difficulty is occasioned by ASA’s sensitivity to heat while being printed. However, after printing, ASA print remains quite a heat-resistant and durable product.
