INFINAM® TPA

Thermoplastic amide powders (elastomers)

Evonik has developed the world's first flexible plastic material based on TPA (thermoplastic amide) stands out for its high elasticity and strength and is suitable for a variety of powder-based 3D printing technologies.

flexible plastic material based on TPA

INFINAM® TPA powder from Evonik 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.

3D printed parts made from the TPA powder show a high degree of flexibility, excellent resistance to chemicals and outstanding durability over a wide temperature range from -40°C to 90°C. The powder is also ideally suited for the manufacture of functional 3D high-tech plastic parts – for prototypes as well as series products.

Suitable for HP’s Multi Jet Fusion technology

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 similar to that of HP’s branded PA12 polyamide.
