OEM Desktop Metal has announced the qualification of Evonik photopolymers and materials for its ETEC Xtreme 8K and the Pro XL 3D printers. As a reminder, ETEC was previously known as EnvisionTEC, a 3D printer manufacturer Desktop Metal purchased in 2021.
INFINAM® ST 6100 L from specialty chemicals company Evonik is the material at the heart of this partnership. The photopolymer features an ultimate tensile strength (UTS) of 90 MPa, flexural stress of 135 MPa, and heat deflection temperature (HDT) of 120 °C. It also delivers exceptional accuracy, surface finish, and resistance to many chemicals and UV degradation.
“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,” said 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.”
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. Additionally, tools or parts 3D printed in INFINAM® ST 6100 can deliver very precise features and a smooth surface finish, especially when paired with the crisp 65 μm resolution offered on the ETEC Pro XL. Parts printed in this material can also be machined and polished, in addition to other post-processing techniques, a press release reads.
“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,” Vitor Lavini, head of Evonik’s photopolymer market segment in the company’s Additive Manufacturing Innovation Growth Field said.
