## Summary description

Sunlu ASA filament in red is a 1.75 mm engineering thermoplastic intended for 3D printing durable, weather-resistant parts. ASA offers UV and heat stability compared with standard PLA, making it suitable for outdoor components, functional prototypes, housings and mechanical parts. Use with heated bed and appropriate print settings for best layer adhesion.

## Long description

Sunlu ASA 3D Printer Filament in red is a 1.75 mm engineering thermoplastic formulated for durable, weather-resistant parts. It combines UV and heat stability with mechanical strength to retain color, shape and functional properties after prolonged outdoor exposure. Diameter tolerance of ±0.02 mm and smooth extrusion support consistent print quality for functional prototypes, housings and outdoor components.
Advantages
ASA provides high resistance to UV radiation, rain and elevated temperatures while offering superior tensile and impact strength compared with common consumer filaments. The material exhibits good layer adhesion and dimensional stability, a high heat deflection temperature, and a print-ready consistency that reduces clogging and ensures predictable extrusion.
Suitable for
Outdoor enclosures and housings for electronics
Automotive trims and exterior fixtures
Functional prototypes and mechanical parts exposed to weather
Landscaping elements and exterior signage
When it may not be suitable
ASA is not ideal for fine decorative prints where a glossy, mirror-like finish is the primary goal; post-processing such as sanding or coating may be required to achieve that appearance. It also requires a heated bed and controlled printing temperatures, so it may not be the best choice for entry-level printers that cannot reach the recommended settings or maintain stable extrusion.
Key specifications
Material: ASA (acrylonitrile-styrene-acrylate)
Filament diameter: 1.75 mm (±0.02 mm)
Density: 1.05 g/cm³

Flexural strength: 73 MPa
Flexural modulus: 2144 MPa
Elongation at break: 20%
Impact resistance: 18 kJ/m²
Weather resistance: high resistance to UV, rain and temperature
How to use
Print with a nozzle temperature in the recommended range (250–280°C depending on speed) and a heated bed set to 80–100°C to reduce warping and improve adhesion. Use a sealed or semi-enclosed build chamber if possible and keep filament dry (store under \<20% RH with desiccant). Adjust print speed between 50 and 200 mm/s according to detail and part size; slower speeds favor finer detail and stronger interlayer bonding. After printing, allow parts to cool gradually on the build plate to minimize distortion.
What to consider before purchase
Require a printer capable of reaching 250–280°C nozzle temperatures and a heated bed
Best used with a sealed or semi-enclosed printer or controlled ambient conditions
Plan for filament drying and storage to maintain print quality
May need post-processing for cosmetic surface finish
Usage recommendations
If you need durable, weather-resistant parts, set nozzle temperature according to your print speed, keep the bed at 80–100°C, use a heated chamber or enclosure when possible, and store the filament dry to preserve mechanical and visual properties.
