The Definition of ASA 3D Printing Filament
ASA stands for Acrylonitrile Styrene Acrylate. It’s a thermoplastic filament prized for its outstanding mechanical properties and excellent weather resistance. It has many similarities to ABS, but with more strong UV resistance, which means more durability outdoors.
In short:
ASA = ABS + Better Weather Resistance
Why Is ASA So Popular? The Big Five Benefits
1. UV Resistance & Weather Resistance
The ASA has excellent resistance to sunlight oxidation, aging, and water, which ensures that items printed with ASA maintain their integrity and vibrancy even when exposed to the outdoors for long periods.
2. Heat Resistance
ASA can withstand higher temperatures, over 90°C at 1.8MPa circumstances, compared to PLA and PETG. The products can keep shape and strength even in hot environments.
3. High durability and strength
ASA has solid mechanical properties, can hold 38MPa tensile stress. It’s perfect for functional parts that need toughness, stability, and long-term performance.
4. Smooth Surface Finish
Using ASA to print will have a clean, matte look with fewer layer lines, making the final result more professional. Also, it can be sanded or painted to achieve a smooth finish.
5. Chemical Resistance
Oils, salts, and fuels? ASA can handle it. That’s why industries like automotive, construction, and outdoor equipment rely on this material.
ASA Wide Application Scenarios
✅ Automotive parts (clips, brackets, covers)
✅ Outdoor equipment (fixtures, gardening tools)
✅ Functional mechanical parts
✅ Signage and display boards
✅ Sports or camping accessories
✅ Drones & RC components
✅ Industrial prototypes

A Few Simple Tips for ASA Printing
Once your settings are tuned, ASA prints beautifully and consistently.
Bed temperature: 80–100°C
Nozzle temperature: 240–270°C
Part Cooling fan: 0-70%
Enclosed printer is highly recommended (maintain heat, prevent warping, and stable printing)
Good ventilation (ASA emits some fumes)
