Polymaker ASA Filament: Characteristics, Benefits, and Printing Tips
Polymaker has been in the 3D printing industry for over 10 years, earning a reputation as a manufacturer trusted by makers worldwide. In this article, we cover Polymaker ASA filament — a material with outstanding resistance to external factors that has long been a popular choice for engineering and outdoor applications. Be sure to read to the end for practical printing tips.
What is ASA?
ASA (Acrylonitrile Styrene Acrylate) is a thermoplastic with properties similar to ABS, which is even reflected in their names. However, the key difference is exceptional weather resistance, making ASA the ideal material for outdoor products. The filament entered mass production in 2019 and became part of Polymaker's most popular material line.
Key Properties
Most plastics turn yellow and become brittle under sunlight. Polymaker ASA does not. Thanks to its UV resistance, parts maintain their appearance and characteristics even after prolonged exposure to direct sun.
The material is also resistant to environmental stress cracking: printed models withstand high humidity and rain for long periods without losing strength.
In terms of mechanical and thermal properties, Polymaker ASA surpasses similar ABS — a fact confirmed not only by technical specifications but also by real-world projects.
Advantages of Polymaker ASA
Polymaker specialists were involved in developing the material for the world’s largest 3D-printed pedestrian bridge project, implemented by the Shanghai Construction Group. Through extensive testing, the brand mastered new compounding formulas and perfected its production technology. The result is a material with several advantages over competitors:
- Significantly higher strength levels compared to competitors;
- Best-in-class melt flow index — easy and smooth extrusion;
- Exceptional interlayer adhesion.
Printing Tips
- Use an adhesive. ASA is prone to warping, so it is recommended to apply Magigoo to the build surface — this significantly reduces the risk of the first layer peeling.
- Turn off the cooling fan. This reduces warping and splitting during printing.
- Use a closed enclosure for large parts — stable temperature inside the chamber greatly improves the quality of the finished model.
