Arnitel® AM3001 (P)

Soft elastomeric powder that is easy to print

Soft elastomeric material for SLS printing that combines high energy return with easy printing

Arnitel®* AM3001 (P) is a thermoplastic elastomer material for SLS 3D printing technology that combines high energy return with easy processing. The soft elastomer meets the requirements of the European Toy Safety Directive 2009/48/EC and is pending biocompatibility approval.

Soft, rubber-like polymer materials are widely used in sports and lifestyle such as footwear, sports guards and protective gear. Additive manufacturing is a production technology well suited to the sports and lifestyle market as it allows for cost-efficient personalization and customization. Actual adoption, however, will require availability of materials that combine the right property set with easy printing and a technology that can scale economically.

Typically, soft and elastomeric materials don’t 3D print easily. In Arnitel® AM3001 (P) for SLS, Covestro material scientists managed to successfully combine both. A Shore Hardness of A88 and D35 with elongation at break of the thermoplastic copolymer (TPC) exhibits a very high energy return - above the 50-60% usually found in footwear materials. The Arnitel®  powder designed for SLS printing is easy to process without common side-effects such as odors.

The material will be available for customer evaluation and development early H1, 2022.
