ASA is designed for real-world conditions: it provides high resistance to UV radiation, moisture, and temperature fluctuations. Prints therefore last longer without fading, becoming brittle, or deforming – ideal for enclosures, brackets, garden parts, and installation components.
Thanks to its mechanical properties (e.g., tensile strength 50 MPa and impact resistance 18 kJ/m²), the filament is suitable for components that must withstand long-term loads. It is great for technical prototypes, car parts, or electronic enclosures.
Diameter accuracy ±0.02 mm and even winding support smooth feeding and consistent extrusion. The result is cleaner layers, better dimensional accuracy, and reliable printing even for more demanding models (illustrative print example).
Sunlu ASA (acrylonitrile styrene acrylate) is a material designed for situations where standard PLA or ABS often isn’t enough. Prints maintain their color and shape over the long term when exposed to sun, moisture, and temperature changes, making it an excellent choice for outdoor components, enclosures, brackets, automotive accessories, or technical prototypes.
The filament supports stable printing at recommended temperatures and offers very good layer adhesion. You’ll appreciate it when producing parts that must withstand mechanical stress while still looking clean and detailed.
