ASA Filament Price Comparison

ASA filament — specifications and use cases

ASA (Acrylonitrile Styrene Acrylate) is the improved ABS variant, formulated for UV and weather resistance. Print temperature: 230–260 °C, bed at 90–110 °C, enclosure recommended. Perfect for outdoor parts exposed to sunlight — equipment enclosures, signage, camera mounts, automotive trim. Unlike ABS, it does not yellow under UV exposure and maintains its color over time. Advantages: color stability, UV resistance, mechanical properties similar to ABS. Disadvantages: less available than ABS, slightly higher price. For outdoor applications where ABS would degrade within months, ASA maintains structural integrity and color fidelity for years. Typical price on Amazon: $15–25/kg.
