New polyamides for advanced sintering processes
Evonik and HP develop 3D-printable thermoplastic elastomer to enable breakthrough applications for HP’s Multi Jet Fusion™ technology.
Evonik and HP’s new TPA powder is a flexible, lightweight-construction material distinguished by its very low density of 1.01 g/cm³ and a Shore A hardness of 91. The high-performance powder is excellently suited for production of functional high-tech 3D plastic parts—prototypes as well as series products—that call for high extensibility and energy return, such as sports equipment or automobile components.
The new ready-to-use powder material meets all the processability criteria required for optimized, production-grade parts developed for HP’s Multi Jet Fusion™ technology. The powder enables fast, high-quality parts to be produced using HP’s Jet Fusion 4200 series of 3D printers, resulting in an efficient, reliable experience.
The advantages are twofold: The process works about ten times as fast as other additive processes, and the indirect fusion protects the polymer chains so that the defined properties of the material are retained. Evonik participates in HP’s Open Platform Program and provide additional powder materials for Multi Jet Fusion™ technology.
Evonik has developed the world's first flexible plastic material based on TPA (thermoplastic amide) stands out for its high elasticity and strength.
