ASA, also called Acrylonitrile-Styrene-Acrylate. The filament is a widely recognized thermoplastic polymer, best known for its use in outdoor and functional applications. Compared with PLA, PETG, and ABS, ASA filament offers superior heat resistance, UV resistance, and weather resistance, preventing the parts from cracking, discoloration, and brittleness
In this article, we’re not talking about specifications on paper. Instead, we show real models that people actually print and use outdoors, and provide inspiration for your outdoor printing project.
Outdoor applications
📍 Automotive Exterior Accessories
The interior & exterior car accessories are often exposed to sunlight for a long time. Compared to ABS materials, ASA performs better in high heat and UV circumstances. That’s why it is often used for automotive parts, such as this seat hook.

Why Use ASA for Outdoor Applications?
✔Superior UV resistance: no yellowing and cracking
✔ Weather resistance: withstand rain, temperature, and wind
✔ Excellent heat resistance: keep good performance in hot environments
✔ Solid mechanical properties: better for functional parts
✔ Chemical resistance: handle fuels, oils, salts, etc.
If you need prints that can withstand sun, rain, heat, and pressure for a long time, ASA is one of the most reliable filament choices.
At iSANMATE, we are committed to producing ASA filaments suitable for various applications widely and continually improving the material to achieve more stable and repeatable outdoor printing.
