eSUN ASA UV Resistant Black 3D Printer Filament 1.75mm 1KG

Product Description

eSUN ASA is a high-performance 3D printing filament engineered for outdoor and industrial applications. Known for its excellent UV resistance, weatherability, and mechanical strength, ASA is the ideal alternative to ABS when long-term exposure to sunlight and harsh environmental conditions is required. It offers strong impact resistance, a smooth surface finish, and high dimensional stability—making it perfect for functional prototypes, automotive parts, and outdoor-use objects.
