SUNLU ASA 3D Printer Filament – 1kg
Durable, Weather-Resistant Filament for Outdoor & Functional Parts
SUNLU ASA Filament is engineered for strength, impact resistance, and UV stability, making it an excellent choice for outdoor-exposed prints, mechanical components, and functional prototypes. ASA (Acrylonitrile Styrene Acrylate) combines the ease of printing found in PLA with enhanced thermal and weather resistance, delivering reliable performance for both hobbyists and professionals.
Outstanding Outdoor Performance
ASA’s inherent UV resistance makes this filament ideal for items that will be exposed to sunlight, changing temperatures, and moisture. Models retain their mechanical integrity and colour stability over time, making them suitable for outdoor fixtures, automotive parts, sporting accessories, and functional housings.
Strong and Impact-Resistant
Designed for rugged use, SUNLU ASA offers excellent impact strength and dimensional stability. It resists cracking, warping, and deformation under stress, delivering durable prints that hold up well when used in demanding environments or load-bearing applications.
Reliable Printing with Smooth Results
This ASA filament prints with consistent extrusion and good layer adhesion, minimising common issues like shrinkage and warping when proper print settings are used. It behaves similarly to ABS in mechanical performance but with improved weather resistance and less odour during printing.

Recommended Print Settings & Tips
To reduce the risk of warping and improve first-layer adhesion, use an enclosed build chamber or controlled ambient temperature. A heated bed set within the recommended range helps maintain consistent adhesion and reduces curling on larger parts.
Ideal Applications
Outdoor components and fixtures
Automotive and drone parts
Functional prototypes and end-use pieces
Enclosures, brackets, and structural models
Weather-exposed prints requiring UV resistance
Built for Strength and Weather Durability
SUNLU ASA Filament offers the perfect balance between ease of printing and outdoor performance. It is a dependable material choice for projects that must endure sunlight, temperature changes, or regular use without sacrificing print quality or mechanical reliability.
