ASA is a technical material with properties similar to ABS, but better in several aspects. Compared to ABS, it is resistant to ultraviolet radiation (UV stable), has less pronounced shrinkage, and the fumes produced are much less noticeable. 3D prints with ASA are durable, hard, and suitable for a wide range of applications. ASA has much better resistance to high temperatures than other common materials such as PLA or PETG. It shows no signs of deformation up to temperatures close to 93°C. Thanks to all these properties, ASA is particularly suitable for printing objects intended for long-term outdoor use.

Printing Settings

• Nozzle: 260±5 °C
• Heatbed: 110±5 °C
• Recommended Steel Sheet: Satin

Key Features

• Ideal for outdoor use – resistant to UV radiation
• Good resistance to high temperatures
• Detailed prints without pronounced “stringing”
• Can be smoothed with acetone vapors
• Can be sanded / post-processed easily
• Good mechanical strength
• Large models tend to warp
• Produces a slight burnt plastic smell during printing (less than ABS)
• Requires an enclosed chamber (enclosure)
• Contains styrene (potentially harmful fumes)
• Slightly hygroscopic (absorbs moisture)
