SUNLU ASA Filament 1.75mm, UV/Rain/Heat Resistant Tough 3D Printer Filament, Great for Printing Outdoor Functional Mechanical Parts, 1kg Spool (2.2lbs)
  • SUNLU ASA 3D Filament: ASA filament is kind of very strong and tough filament, stronger than PLA filament and ABS filament. No clog, no bubble, no tangle, good layer adhesion, easy to use.
  • Super Neat Filament Spool, Spool Diameter: 8.00", Spool Width: 2.50", Spool Hub Hole Diameter: 2.20". The size of the SUNLU filament spool is suitable for hanging on a lot of FDM 3D printers.
  • 1.75mm Filament Diameter, Dimensional Accuracy +/- 0.02mm. SUNLU filament has wide compatibility due to the small diameter error, it's suitable for almost all 1.75mm FDM 3D printers.
  • Recommend Settings, We recommend printing at a nozzle temperature of 

    250-260℃, printing speed of 50 -100mm/s or 260-280℃, printing speed of 100-200mm/sbed temperature of 90-110°C.

  • UV/Rain/Heat Resistant, SUNLU ASA 3D printing filament is great for printing outdoor functional mechanical parts, UV/Rain/Heat highly resistant.
  • SUNLU Professional Team, SUNLU is a high-tech enterprise specializing in R&D, production and sales of 3D filament, 3D printer, 3D pen, filament dryer, 3D resin and resin UV light curing box.

 

UV resistance prevents yellowing, Waterproofing withstands rain/humidity, and heat resistance up to 90°C—perfect for automotive parts, outdoor tools, and functional prototypes exposed to extreme conditions.

Weather resistance & UV resistance

SUNLU ASA Filament is a high-performance 3D printing material designed for outdoor use.

It offers exceptional weather resistance, effectively withstanding UV rays, rain, and high temperatures, ensuring it remains fade-resistant and shape-stable even after prolonged exposure to outdoor conditions.

With its high strength and excellent toughness, ASA is both durable and resilient, making it ideal for parts or structures that must endure long-term external stress.

Thanks to its outstanding mechanical properties and weather resistance, ASA is widely used in industries such as automotive components, architectural facades, and garden equipment, making it the top choice for projects requiring longevity and reliability.

Proven Printing Tips for Perfect Results

Achieve flawless ASA prints with SUNLU’s expert-tested guidelines:

Temperature Control: Optimize nozzle temps between 250–280°C for smooth flow without oozing.

Adhesion Mastery: Use an 90–110°C heated bed with glue stick or PEI sheet to eliminate warping.

Speed & Cooling: Recommend printing at a nozzle temperature of 250-260°C, printing speed of 50-100mm/s; emperature of 260-280°C, printing speed of 100-200mm/s, bed temperature of 80-120°C(176-248°F)

Enclosed Printing: Minimize drafts and stabilize chamber temps (~50°C) to prevent cracking.

Filament Care: Store in sealed bags with desiccant between prints to preserve performance.
