ASA is an excellent choice for prints exposed to sun, moisture, and temperature fluctuations. It provides high resistance to UV radiation and weathering, making it suitable for outdoor installations, garden elements, and technical parts with a long service life.
The tolerated diameter accuracy of 1.75 mm (±0.02 mm) supports stable feeding and consistent layering. The filament is designed for smooth nozzle flow and even extrusion, helping you achieve clean surfaces and reliable printing results.
SUNLU ASA offers tensile strength of 50 MPa and good impact resistance, making it suitable for functional components, enclosures, and mechanically stressed parts. At the same time, it shows dimensional stability and resistance to thermal deformation, which is key for precise assemblies.
SUNLU ASA filament (acrylonitrile styrene acrylate) is designed for demanding applications where common materials like PLA are not enough. Thanks to the combination of mechanical durability and UV resistance, prints retain their shape, properties, and color even during long-term exposure to sun, rain, and temperature changes.
The material is optimized for stable 3D printing—it offers good layer adhesion and smooth extrusion, which helps achieve consistent results both for functional prototypes and for final parts.
