Desktop Metal and Evonik, a materials provider in 3D printing technology based in Germany, report their expanded collaboration on photopolymer and materials development with the qualification of INFINAM ST 6100 L on the ETEC Xtreme 8K and the Pro XL.

Evonik INFINAM ST 6100 L is a benchmark material in high-strength photopolymers for 3D printing. With a tensile strength (UTS) of 90 MPa, flexural stress of 135 MPa, and heat deflection temperature (HDT) of 120°C, the material reportedly also delivers accuracy, surface finish, and resistance to many chemicals and UV degradation.

Desktop Metal’s ETEC brand for polymer 3D printing is vested in digital light processing (DLP) hardware and a curated portfolio of additive manufacturing materials.

“Desktop Metal is delighted to add Evonik and its INFINAM material to our highly selective portfolio of polymers, as we continue to offer customers the flagship material solutions in each performance class, ranging from stiff rigid plastics to high strength-to-weight ratio elastomers and foams,” says Walter Voit, senior vice president for Polymer Materials at Desktop Metal. “Our hardware systems offer the size, speed, and quality required for high-throughput Additive Manufacturing 2.0 production of premium photoresins like ST 6100L.”

“Collaboration with customers and partners is an important driver of innovation for us,” says Vitor Lavini, head of Evonik’s photopolymer market segment in the company’s Additive Manufacturing Innovation Growth Field. “The validation of ST 6100 L on Desktop Metal’s printers—especially the ETEC Xtreme 8K—fits with Evonik’s vision that larger and faster DLP printers will increase productivity, substantially reduce costs per part and enable series production in the long run.”

The properties offered by INFINAM ST 6100 L make the material ideal for 3D printed production of molds, models and tooling, as well as end-use parts in the aerospace, automotive or electronics industries, according to the companies. Parts printed in this material can also be machined and polished, in addition to other post-processing techniques.
