FDM TPU 92A

Production-grade Elastomer

FDM® TPU 92A is a thermoplastic polyurethane with a Shore A value of 92. The material exhibits high elongation, superior toughness, durability and abrasion resistance.

FDM TPU 92A brings the benefits of elastomers to FDM 3D printing and offers the capability to  quickly produce large and complex elastomer parts. Typical applications include flexible hoses, tubes, air ducts, seals, protective covers and vibration dampeners. FDM TPU 92A is available on the F123™ Series 3D Printers and is compatible with QSR™ soluble support material.

Milwaukee School of Engineering (MOSE) beta test the FDM TPU 92a on the Stratasys F123 for creation of their product designs.

The definition of a good elasomer is it can bend, stretch and then return to it's orginal shape. The new FDM TPU 92a material from Stratasys provides those chacteristics. Elastomers are now in demand for production of medium to large sized production parts and manufacturers need Stratasys machines to build their prototypes and short production runs.

Fused Deposition Modeling (FDM) Technology

Advantages of 3D printing FDM TPU 92A 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. FDM TPU 92A 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.
