SUNLU ABS B ABS 1.75 mm, 1 kg 3D Printer Filament, Black

SUNLU ABS B ABS Filament, Black, 1.75 mm, 1 kg is a black acrylonitrile butadiene styrene material for fused filament fabrication (FFF/FDM) 3D printers. It is engineered for functional parts, durable prototypes, and replacement components that require higher strength and wear resistance than general-purpose plastics. Printed objects can be drilled, tapped, sanded, and painted, making the material suitable for engineering, automotive, and workshop applications. It provides a tensile strength of 42,000 kPa and a flexural strength of 55 MPa. The 1.75 mm diameter is held to a tolerance of 0.03 mm for consistent extrusion.

Optimal printing requires a nozzle temperature of 250 °C and a heated build plate set between 80 and 100 °C. A maximum nozzle temperature of 280 °C is supported, with a recommended print speed of 50 mm/s. Because ABS is prone to warping as it cools, an enclosed printer or a controlled environment is recommended for reliable results. The filament is compatible with standard FFF/FDM systems that support 1.75 mm filament, including setups designated for the Bambu Lab AMS. Users should store the material in environments with a relative humidity below 20%.
