ASA
Production-grade Thermoplastic
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 for Stratasys Fused Deposition Modeling production 3D printers.
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 production parts for outdoor commercial and infrastructure use. And its wide selection of colours and matte finish makes it ideal for attractive prototypes in consumer sporting goods, tools and automotive components and accessories.
