ASA provides consistently high-quality, production grade parts with exceptional UV stability and the best aesthetics of any FDM® thermoplastic; ASA is poised to become the most popular all-purpose material. Matching or exceeding the mechanical properties of ABS, its UV-resistance makes it especially suited in end-use parts for outdoor commercial and infrastructure use, and its wide selection of colors and matte finish makes it ideal for attractive prototypes in consumer sporting goods, tools and automotive components.
