Evonik, a specialty chemicals company, is extending its portfolio of elastomeric materials for powder bed fusion 3D printing technologies with the launch of INFINAM TPA 4006 P – a new powder grade that is optimized for all types of open-source SLS 3D printing machines. Evonik will present its new flexible material at Formnext, on November 7-10, 2023.

INFINAM TPA 4006 P is a PA12 elastomer consisting of polyamide 12 segments and softening segments and is characterized by rubber-like properties, outstanding impact strength – and thus excellent rebound behavior.

Evonik’s new 3D printing elastomer features high process stability and excellent powder flow properties. Furthermore, the fine powder can be manufactured with reusability rates of 50% virgin material and 50% used material.

“Elastomer-based 3D printing applications play a crucial role of the additive value proposition. Mostly like limited editions of infinite designs or high customization they perfectly showcase what 3D printing stands for,” said Arnim Kraatz, Director of Powder Bed Fusion at Evonik. “By offering new optimized 3D printing materials, we enable our customers to take advantage of the unique set material properties in order to explore and scale up new applications.”

3D printed parts from INFINAM TPA 4006 P show an excellent surface resolution and feature detail while exhibiting outstanding durability over a wide temperature range – from -40°C to 90°C. The powder is also ideally suited for the manufacturing of functional 3D high-tech plastic parts – for prototypes as well as series products. TPA has been used, for decades, as the material of choice for a variety of consumer goods applications like footwear (check out our article on Footwearology’s recent FootPRINT3D event for more information about how the footwear industry is adopting the use of 3D printing technology).


Evonik’s range of elastomeric 3D printing materials includes two types of powders for powder bed fusion 3D printing, including thermoplastic amide INFINAM TPA, and thermoplastic copolyester INFINAM TPC. INFINAM FL, a rubber-like photopolymer resin for photo-curing 3D printing, completes the current portfolio of elastomeric materials for industrial 3D printing.
