SUNLU ASA technical filament is an ideal choice for durable outdoor prints and functional parts. It offers high UV resistance, excellent mechanical strength, dimensional stability, and reliable extrusion with a diameter accuracy of ±0.02 mm for consistent results.
Outdoor durability without compromise
ASA is designed for real-world conditions: it offers high UV resistance and withstands rain and temperature fluctuations. Prints deform less and retain their appearance and functional properties over the long term.
Strong and tough parts for functional use
Thanks to a tensile strength of 50 MPa and high impact resistance, the filament is suitable for parts exposed to mechanical stress—from holders and covers to technical components.
Precise diameter and smooth extrusion
The 1.75 mm diameter accuracy (±0.02 mm) supports consistent material feeding and stable printing. The result is reliable layer quality, good detail, and a smooth printing process at the recommended temperatures.
SUNLU ASA (acrylonitrile styrene acrylate) is a premium 3D printing material designed for situations where standard filaments are not enough. Prints retain their color and shape over the long term, even when exposed to sunlight, moisture, and temperature changes. This makes it excellent for outdoor applications, prototypes, and final functional parts.
Why choose SUNLU ASA:
- Outdoor durability – high resistance to UV radiation, rain, and temperature fluctuations
- Strength and toughness – suitable for stressed components and long-term use
- Stable printing – excellent layer adhesion and dimensional stability
- Precise 1.75 mm diameter (±0.02 mm) – smooth feeding and consistent extrusion
The material is optimized for professional printing across a wide range of speeds. Recommended nozzle and heated bed temperatures help achieve a high-quality surface even on larger parts that require a stable process.
