FDM – ASA

ASA (Acrylonitirle Styrene Acrylate) is a UV-resistant, famously weatherable polymer. ASA has a low-gloss matte finish which makes it the perfect filament for technical-looking prints, especially when you don’t want the high-gloss surface finish often associated with 3D printing materials like ABS, PETG, or PLA.

Key Material Facts:

• UV & Weather Resistance – Unlike ABS, ASA doesn’t yellow or become brittle when exposed to sunlight.
• High Impact Strength – Durable and resistant to cracks or breaks.
• Good Chemical Resistance – Holds up well against many chemicals and solvents.
• Heat Resistance – Similar to ABS, can withstand moderately high temperatures.
• Matte Finish – Provides a smoother, less glossy appearance than ABS.
• Less Warping than ABS – Still requires a heated bed but has better layer adhesion and less warping.

Common Applications:

• Outdoor signage & enclosures
• Automotive parts
• Sporting goods
• Prototyping durable end-use parts
