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

The SUNLU ASA R ASA Filament 1.75 mm 1 kg Red is formulated for Fused Filament Fabrication (FFF) and FDM 3D printers and is aimed at functional and outdoor components. Its acrylonitrile styrene acrylate (ASA) composition offers inherent UV and weather resistance, making it suitable for parts exposed to sunlight, rain, and heat. The filament comes on a 1 kg spool with a 1.75 mm diameter and an approximate length of 395 metres. It holds good mechanical durability, dimensional stability, and layer adhesion in demanding environments, and the printed material has a glass transition temperature of 96 °C, helping it keep its structural integrity in moderately high-temperature applications.

For reliable extrusion, the filament has a diameter tolerance of ±0.02 mm, which lowers the risk of clogging and tangling during printing. It needs a minimum nozzle temperature of 250 °C, with a supported range up to 280 °C, and a heated build plate set between 80 °C and 100 °C. The material shows a flexural strength of 68 MPa, a flexural modulus of 2300 MPa, and an impact strength of 7 kJ/m². A controlled printing environment with relative humidity below 20% is recommended. The spool is fully compatible with Bambu Lab AMS systems and standard FDM/FFF printers that accept 1.75 mm filament.
