Bambu Lab ASA Blue (1.75mm, 1kg) is an outdoor-grade engineering filament that combines the printability of ABS with significantly improved UV stability and weather resistance. ASA is the go-to material for parts that are permanently exposed to sunlight, rain and temperature fluctuations, making it ideal for outdoor enclosures, signage, garden accessories, automotive trim and architectural models.

Clean outdoor blue suits nautical, garden and infrastructure applications where UV stability is critical. Like ABS, ASA benefits from an enclosed printer and a heated bed to prevent warping, and it can be post-processed by sanding, drilling and painting. It is compatible with the Bambu AMS for multi-colour outdoor projects.

Key features

• High UV and weather resistance - retains colour and mechanical properties after prolonged outdoor exposure.
