ASA

Now you can build consistently high-quality parts with exceptional UV stability and the best aesthetics of any FDM thermoplastic. ASA is poised to become the most popular all-purpose prototyping material.

Matching or exceeding the mechanical properties of ABS, ASA may be your new favorite general prototyping material. Its UV-resistance makes it especially suited in end-use parts for outdoor commercial and infrastructure use.

Its matte finish makes it ideal for attractive prototypes in consumer sporting goods, tools and automotive components and accessories.

Color options: Ivory, white, light gray, dark gray, black, red, dark blue, green, yellow, and orange
