ASA 3D Printing ASA is a weather-resistant alternative to ABS, which has excellent UV stability, temperature resistance and chemical resistance. This makes ASA ideal for outdoor applications. , GET QUOTE About 3D Printing With ASA ASA filament is similar in composition to ABS, but uses acrylates instead of butadiene. This gives ASA excellent UV stability, enhanced toughness, high impact resistance, and improved temperature resistance, and can be made in a variety of colors that do not fade or yellow easily when exposed to sunlight. ASA is an ABS modified material with excellent UV and impact resistance, ideal for outdoor applications…
