ASA is an excellent choice for parts exposed to sunlight and weather. It features high resistance to UV radiation, rain and temperature fluctuations, so prints retain their color over the long term and do not fade or deform.
Thanks to a diameter tolerance of ±0.02 mm, the filament provides stable extrusion and consistent print quality. The spool supports smooth unwinding of the material for reliable operation during long prints.
The filament is evenly and neatly wound, helping to reduce the risk of tangling and contributing to smooth feeding into the printer. The result is a more stable process and cleaner prints.
SUNLU ASA filament (acrylonitrile styrene acrylate) is designed for projects where standard materials are not sufficient. Thanks to its combination of mechanical strength and resistance to weathering, prints retain their color, shape and functional properties over the long term – even when exposed to sunlight, moisture or temperature fluctuations.
The material is optimized for stable printing and professional results. Precise diameter tolerances support a uniform material flow and a clean surface without unnecessary fluctuations in extrusion.
