ASA (Acrylonitrile Styrene Acrylate) is a synthetic, amorphous thermoplastic that works best in material extrusion printing. It is a high impact material that can be used to produce functional parts for automotive applications, electronics, tooling, and more. In addition, it is known for having high weather and UV resistance, making it a great candidate for outdoor applications.

ASA filament is used instead of ABS for mechanical parts that need durability. But there is a difference between ABS and ASA in properties, price point and work each material requires from you. In recent times ASA became more affordable and improvements in desktop FDM printers allow to work with it well. It still requires a well-leveled bed, good heating capabilities, correct cooling process, and adhesion improvements.

The end prints made with ASA are sturdy and stiff like ABS but on top of that, they would withstand weather and sun much better. Some people also notice that ASA may be more tactile pleasant than ABS.

[Print Effect]
Standard: Support structures are removed and some light sanding is performed at the support locations. FDM parts will generally show clear layer lines known as stepping. If a smooth surface finish is required right off the machine, then they should consider other 3D printing technologies.
Custom: Custom surface finishes like painting and additional sanding can be requested.


Good UV resistance
Nice glossy surface, which is pleasant to tough
Tough and strong
Chemically resistant
Lower color fade
Can be smoothed with a solvent like acetone


ASA is hygroscopic, which means it absorbs water from the air
May be tough to work with
May produce toxic smoke when burnt
Some grades and filaments cost much
ASA melts with some other plastics giving rise to moldings of poor strength
Can't withstand some concentrated acids, hydrocarbons, esters, ethers and ketones
