3DElastoPrint is enabled by an elastomeric TPA, co-branded by Evonik and HP — a flexible, high-performance, thermoplastic elastomer optimized specifically for HP’s Multi Jet Fusion (MJF) 3D printer.
Evonik and HP’s TPA material is flexible and lightweight, distinguished by its low density of 1.01 g/cm³ and a Shore A hardness of 90. This high-performance material is suited for prototypes as well as end-used products that call for high extensibility and energy return, such as sports equipment, automobile components, and end-of-arm tooling.
Potential applications include:
Using HP’s powder-bed technology, 3DElastoPrint TPA material allows for exceptionally complex geometries at a fraction of the cost of traditional technologies. With high fatigue resistance, it can be bonded into wearables, footwear, protective gear, eyewear, and a variety of sporting equipment.
Ducting and bellows
Traditionally, ducting is challenging to produce in low quantities because of the tooling required to produce difficult undercuts, thin walls, and tricky geometry for soft materials. But our 3DElastoPrint service solves these problems with this newly released, highly durable, production-grade, TPA elastomer. The material has high energy return and high fatigue resistance, capable of thousands of flexes. And, due to MJF technology, it is perfect for parts with large undercuts & trapped volumes.
End of arm tooling
End-of-arm tooling is at the forefront of “new engineering required” because shapes are often amorphous, the weight needs to be optimized, and material properties can dramatically affect the performance. 3DElastoPrint parts can be latticed, hollow, topology-optimized, and light-weighted works of engineering mastery.
