ASA Filament

The material has been specially developed to be more resistant to weather conditions. ASA is a 3D printer filament that is strong, stiff and relatively easy to print. The material is also extremely resistant to chemical influences and heat. ASA also has less warping than ABS, but the material should not be over-cooled when printing.

Acrylonitrile styrene acrylate (ASA) is a thermoplastic that you can 3D print and has many properties that make it good for engineering and outdoor purposes. ASA is basically the new and improved cousin of acrylonitrile butadiene styrene (ABS) which is more widely known and used (like Lego). ASA has many of the benefits of ABS without some of its drawbacks

ASA, like ABS, is a little difficult to 3D print because it’s sensitive to heat while being printed. However, after printing, ASA parts are very heat-resistant and durable. ASA prints are also rigid and strong, and can even be more so than the same parts made from ABS. Unlike what many users notice with ABS prints, ASA won’t turn yellow when left outside.

In this article, we’ll go over six different ASA filaments and the specifics of each brand. Before that though, we’ll discuss some pros, cons, and uses of the material. We’ll also provide some printing suggestions for working with ASA.


  • It’s mechanically robust feature makes it perfect in terms of applications that require high resistance
  • It is resistant to the U.V. rays which explain its non-yellowing property
  • ASA filament also finds application in the underwater usage or the pump junctions given the fact that it is highly water-resistant
  • It can also generate a good finish for different parts without any kind of deformation
  • It also provides superb dimensional stability with no warping and high tolerance
  • The ASA filament also works well as an element that is resistant to chemicals treatments
  • It also flaunts a higher thermal resistance as compared to ABS
  • Its matte finish towards the surface of the 3D print is something similar to ABS.
