Bambu Lab ASA is a high-quality engineering filament designed for durable and reliable 3D printing of outdoor and demanding parts. The material exhibits outstanding resistance to UV radiation, weather exposure, mechanical stress, and temperature changes, making it an excellent choice for exterior elements, functional components, and structural parts.
ASA delivers low shrinkage, excellent layer adhesion, and dimensional stability, producing clean and consistent prints. It performs reliably on Bambu Lab 3D printers and is compatible with AMS and AMS Lite systems when properly dried before use.
