ASA FDM Plastic

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 users of Fortus 380/450mc™, the Stratasys F900™, and the Stratasys F123™ Series 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.

Fused Deposition Modeling (FDM) Technology

Advantages of 3D printing ASA with a Stratasys FDM Machine

Tough long-lasting parts

FDM technology works with engineering-grade thermoplastics to build strong, long-lasting and dimensionally stable parts with the best accuracy and repeatability of any 3D printing technology. ASA parts are tough enough to be used as advanced conceptual models, functional prototypes, manufacturing tools and production parts.

Meet production demands

FDM systems are as versatile and durable as the parts they produce. Advanced FDM 3D Printers boast the largest build envelopes and material capacities in their class, delivering longer, uninterrupted build times, bigger parts and higher quantities than other additive manufacturing systems, delivering high throughput, duty cycles and utilization rates.

Gain new possibilities

FDM 3D Printers streamline processes from design through manufacturing, reducing costs and eliminating traditional barriers along the way. Industries can cut lead times and costs, products turn out better and get to market faster.
