UV resistantImpact resistantWater resistant

ASA (acrylonitrile styrene acrylate) was developed as an alternative to ABS with substantially better weather resistance. It resists the UV-driven yellowing and embrittlement that affects standard ABS over time, while offering comparable strength and impact resistance, plus somewhat better heat tolerance, holding its shape up to roughly 90 °C. ASA also resists many common chemicals, including weak acids, alkalis, and oils. For parts that are meant to be decorative or for indoor use without high exposure to UV rays, PLA or PETG might be more budget-friendly alternatives. ASA is a strong choice for automotive exterior parts, outdoor enclosures and housings, and garden or furniture components exposed to long-term sun and weather.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

Standard

48 colors

The standard (as-printed) finish on FDM parts shows the natural texture of layer-by-layer printing. The visibility of the layer lines depends on part geometry and orientation, plus light marks where support material was removed.

Sanded

Sanded

48 colors

The sanded finish on FDM parts reduces the visibility of layer lines compared to the standard finish, though some surface texture generally remains. How much smoothness is achieved can vary depending on the material.

Polished
