ASA

Acrylonitrile-styrene-acryl (ASA) is a material with properties similar to ABS. Its main benefit is an increased weather and UV resistance. Another advantage is overall dimensional stability. To achieve a cast-like surface, acetone smoothing can be used.

Sure, ABS is great, but it has its flaws. That’s why plastics manufacturers are always looking for alternatives. One such alternative is acrylonitrile styrene acrylate (ASA), which was originally developed to be a hardy weather resistant material. Hence it’s primary use in the automotive industry.

In addition to being a 3D printer filament that is strong, rigid, and relatively easy to print with, ASA is also extremely resistant to chemical exposure, heat, and mostly importantly, changes in shape and color. Prints made of ABS have a tendency to denature and yellow if left outdoors. Such is not the case with ASA.

Another minor benefit to using ASA over ABS is that it warps less during printing. But be careful with how you adjust your cooling fan; ASA can easily crack if things get a little too windy during printing.
