Sunlu ASA Thread (Black)
SUNLU ASA is a high-quality technical filament, designed for outdoor applications and demanding functional projects. It combines excellent resistance to UV radiation, rain and high temperatures with superior mechanical strength and durability. As a result, printed objects retain their color, shape and properties even after prolonged exposure to adverse weather conditions. The material surpasses PLA and ABS in terms of strength and lifespan, offering excellent layer adhesion and dimensional stability. The diameter accuracy of ±0.02 mm and smooth, jam-free extrusion guarantee high print quality, both visually and technically.

Designed for outdoor use – reliability in all conditions
SUNLU ASA is the ideal choice if you need a material that can withstand real-world conditions. Whether you are designing parts that are exposed to sunlight, humidity or temperature fluctuations, ASA ensures long-term durability without fading or warping. The high warping temperature (96°C) and UV resistance make the prints ideal for automotive, electronics, landscaping and outdoor installations. It is a material that does not let you down when durability matters.

Durability and precision that translate into the final result
Thanks to its high strength (50 MPa), impact resistance and robust structure, SUNLU ASA allows you to create parts that withstand mechanical stress and long-term use. At the same time, the material is optimized for printing — recommended temperatures of 250–280°C and a build plate of 80–100°C ensure a stable process without excessive deformation. The ability to operate in a wide range of speeds (50–200 mm/s) provides flexibility in the production of both fine details and larger projects. This is a filament for those who expect professional quality and full control over the result.
