About ASA (Acrylonitrile Styrene Acrylate) 3D Printing Filament: The Weather-Resistant Powerhouse

Benefits
  • Exceptional UV & Weather Resistance: Unlike ABS, ASA is specifically engineered to withstand prolonged exposure to sunlight, rain, and varying outdoor elements without degrading, discoloring, or becoming brittle. Ideal for outdoor applications.
  • High Dimensional Stability: Maintains its shape and dimensions accurately, even in fluctuating temperatures, making it excellent for precision parts.
  • Excellent Mechanical Properties: Offers high strength, rigidity, and good impact resistance, akin to ABS, ensuring your prints are robust and functional.
  • Good Chemical Resistance: Provides reliable performance when exposed to various chemicals, expanding its utility in demanding environments.
  • Thermal Performance: Exhibits strong thermal properties, allowing it to maintain integrity in higher temperature settings.
  • Versatile Applications: The go-to choice for prototyping outdoor parts, automotive components, drone parts, garden fixtures, electrical enclosures, and any application requiring long-term outdoor durability.
  • Premium USA Manufacturing: Manufactured in the USA using 100% virgin, premium ASA resin, ensuring consistent quality, purity, and superior printability. A direct substitute for ABS where outdoor exposure is a factor.
  • Carefully Packaged: Each reel is precisely spooled, then vacuum-sealed with desiccant to protect against moisture and maintain optimal filament condition.
  • Available in Standard Diameters: Offered in both 1.75mm and 2.85mm diameters to accommodate a wide range of FDM 3D printers.


Warnings and Advisories
  • Enclosure Highly Recommended: While less prone to warping than ABS, an enclosed build chamber is still strongly recommended for ASA to maintain consistent temperatures and prevent drafts, which helps reduce warping and delamination.
  • Ventilation: Like ABS, ASA can produce a noticeable odor and release volatile organic compounds (VOCs) during printing. Ensure adequate ventilation in your printing area.


Recommended Starting Printing Settings
  • Extruder Temperature: 230°C - 240°C
  • Bed Temperature: 80°C - 110°C
  • Print Speed (Typical): 60-90 mm/s (Similar to premium PETG, ASA benefits from a moderate to fast speed range for quality results. For the first layer, maintain 15-25 mm/s for optimal bed adhesion.)

The above settings are general guidelines. The exact optimal settings can vary slightly depending on your specific 3D printer model, the brand of filament, and even environmental factors like room temperature. Always refer to any specific recommendations provided by the filament manufacturer on the spool or packaging.
