SUNLU ASA 1.75 mm, 1 kg 3D Printer Filament, White

The SUNLU ASA W White ASA Filament 1.75 mm, 1 kg is an acrylonitrile styrene acrylate material designed for fused filament fabrication (FFF) 3D printers. It is intended for functional components that need UV and weather resistance for long-term outdoor use. The filament has a nominal diameter of 1.75 mm with a tolerance of ±0.02 mm for consistent extrusion. Printing requires a nozzle temperature between 250 °C and 280 °C. A heated build plate set to 80 °C or 100 °C is needed to manage the high processing temperatures and reduce warping. These parameters make the material suitable for mechanical parts and automotive accessories exposed to demanding environmental conditions.

Structurally, the filament has a flexural strength of 68 MPa and a flexural modulus of 2300 MPa. It shows an impact strength of 7 kJ/m² and a tensile strength of 39000 kPa, with an elongation at break of 11 percent. The material reaches a maximum melting point of 120 °C and a glass transition temperature of 108 °C. These properties help printed parts retain rigidity and toughness under mechanical stress. An enclosed or well-protected printer environment is recommended to keep ambient temperatures stable during the print job. This stability supports the layer adhesion needed for functional prototypes and replacement parts.

• 1 kg spool provides a standard supply for extended printing sessions.
• Bambu Lab AMS compatibility allows for automated material handling on supported devices.
• Print speed capacity of 100 mm/sec enables efficient throughput under optimal conditions.
• Density of 1040 kg/m³ contributes to the overall weight of finished parts.
• Specific gravity of 1.04 g/cm³ determines the mass-to-volume ratio for part design calculations.
• White colouration offers a neutral base for visual identification or post-processing.
