What Is ASA Filament?

• ASA is a high-performance thermoplastic engineered to withstand prolonged UV exposure, moisture, and mechanical stress.
• Originally developed for automotive use, it is now widely used for 3D printed outdoor parts, technical housings, and structural components.
• It offers better weatherability than ABS, with lower yellowing, less warping, and improved dimensional stability.

Why Engineers & Professionals Choose ASA

• UV & Weather Resistance: Excellent color retention and strength outdoors—ideal for signage, tools, and functional parts.
• High Strength & Impact Resistance: Stronger than PLA and PETG, suitable for mechanical loads and end-use parts.
• Thermal Stability: Softening point above 95 °C—suitable for outdoor heat exposure or engine-adjacent use.
• Clean Surface Finish: Matte look with reduced layer lines and strong layer adhesion.

Recommended Print Settings

• Nozzle Temperature: 240–260 °C
• Bed Temperature: 90–110 °C
• Chamber: Recommended for large parts (enclosed printer or draft shield)
• Cooling: Low or disabled for best layer bonding
• Drying: 80 °C for 4–6 hours before use

Applications

• Outdoor enclosures and casings
• Automotive parts and dashboard components
• Tools, brackets, and technical prototypes
• Weather-exposed signage and equipment mounts
