ASA (Acrylonitrile Styrene Acrylate) is an engineering-grade thermoplastic filament designed for FDM 3D printing applications requiring superior weather and UV resistance. As the improved successor to ABS, ASA maintains excellent mechanical properties while eliminating ABS’s primary weakness—sensitivity to ultraviolet radiation. This makes ASA the material of choice for outdoor applications, automotive components, and any parts exposed to sunlight.
Key Properties of ASA Filament
ASA offers excellent UV resistance, maintaining properties under prolonged sunlight without yellowing. With impact strength of 14-20 kJ/m² (Charpy notched), it’s comparable to ABS in toughness. The heat deflection temperature reaches 95-105°C at 0.45 MPa, and water absorption is only 0.5-0.7%, lower than ABS. For precision parts, consider our Sợi PA6-CF with excellent dimensional stability.
ASA vs ABS: The Critical Difference
While both materials offer similar mechanical properties and printability, ASA provides superior UV resistance. ABS typically begins degrading within weeks of outdoor exposure, while ASA maintains its properties for years. For engineering applications, PA66-CF30 offers even higher strength with carbon fiber reinforcement.
Optimal Print Settings
Print ASA at 240-260°C nozzle temperature with a heated bed at 90-110°C. An enclosed print chamber is strongly recommended to minimize warping. Use 40-70 mm/s print speed and 30-50% cooling fan for optimal layer adhesion.
Ứng dụng
ASA is ideal for automotive exterior parts (mirror housings, trim, covers), outdoor equipment and garden tools, drone frames and RC vehicle components, signage and display items, and solar panel mounting hardware.
