ASA
Material Data Sheet
ASA
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.
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
Quick Facts:
- UV stability
- Matches mechanical properties of ABS
- Good for outdoor use
