About Prusament ASA

ASA is a technical material with properties similar to ABS but better in several ways. Compared to ABS, it’s UV stable, it doesn’t suffer from shrinking so badly and the fumes produced are much less noticeable. ASA 3D prints are durable, tough and suitable for a wide range of applications. ASA comes with much better high-temperature resistance than other common materials, such as PLA or PETG. It shows no signs of deformation up to temperatures near 93 °C. Thanks to all these properties, ASA is especially suitable for printing objects meant for long-time outside use.

Beginners tips & tricks

You may encounter some issues related to shrinking (warping) of the material – especially when printing larger models. This effect is much less severe compared to ABS but still, even with the heatbed set to 110°C, the prints can shrink and warp, causing them to detach from the print bed. This issue can be eliminated by printing inside an enclosure (for example our Prusa Enclosure) or by adding a draft shield around the object.

It’s important to run the prints in a well-ventilated room because the material releases fumes and substances that could pose a potential health risk. When ventilating the room, do not create a draft around the print – this will negatively impact the result.
