ASA filament is a high-performance material designed for makers who need strength, UV resistance, and durability in their 3D prints. At Siraya Tech, we’ve built a collection that combines industrial-grade reliability with consistent print quality, perfect for both professional and hobbyist use.
ASA Filament for Outdoor and UV-Resistant Prints
One of the biggest advantages of ASA filament is its ability to withstand prolonged sun exposure without yellowing or degrading. This makes it ideal for outdoor applications where PLA or ABS may fail.
Key Features:
- Excellent UV resistance for long-term outdoor use
- Maintains color and finish in sunlight
- Withstands weathering better than standard plastics
- Durable surface finish with minimal fading

FAQs: ASA Filament
What is ASA filament?
ASA (Acrylonitrile Styrene Acrylate) is a thermoplastic filament known for its strength, UV resistance, and durability. It’s often used in outdoor applications. It offers similar properties to ABS but with better weather resistance.
Is ASA better than PLA?
ASA is more durable and weather-resistant than PLA, making it better for outdoor or functional parts. PLA, however, is easier to print and more beginner-friendly. The choice depends on whether you prioritize strength or ease of use.
Is ASA stronger than PETG?
ASA is generally stronger and more UV-resistant than PETG, especially in outdoor conditions. PETG is easier to print and offers good flexibility. ASA is preferred when durability and weather resistance are top priorities.
Why is ASA so hard to print?
ASA can be challenging because it requires higher temperatures and controlled conditions to prevent warping. An enclosed printer and proper bed adhesion are recommended. With the right setup, ASA prints reliably and delivers excellent results.
