Sunlu ASA 3D printing filament is intended for functional parts and decorative items used outdoors, such as automotive parts, architectural decorations, and garden equipment. It resists UV radiation, rain, and high temperatures, and has a heat deflection temperature of 96 °C. Its 20% elongation at break allows the material to absorb some stress without breaking.

The filament diameter has a tolerance of ±0.02 mm. Its tensile strength is 50 MPa, flexural strength is 73 MPa, and impact strength is 18 kJ/m².
