Evonik introduces 3D printing resin for the production of tough, ductile and flame-retardant parts

Evonik has launched a new photopolymer resin that is both flame-retardant and mechanically resistant after curing. INFINAM FR 4100L has been developed for use with DLP (Digital Light Processing) 3D printers.

“INFINAM FR 4100L is our latest product to address ongoing customer demand for a 3D-printable resin that can meet the unique requirements of aerospace, automotive, and electronics applications,” says Vitor Lavini, head of Market Segment Photopolymers at Evonik’s High Performance Polymers business line. “Fundamental to these market segments are parts that can withstand contact with sparks, flames, and various types of fuels.”

The resin has a certified UL 94 flame retardancy rating of V-0 at a thickness of 3mm. Once cured, the product exhibits high elongation at break, good tactile properties and an excellent surface finish that can be further machined and polished. It also exhibits toughness comparable to ABS (acrylonitrile butadiene styrene) plastic materials.

“Evonik is committed to developing innovative solutions that meet the needs of our customers,” says Dominic Stoerkle, head of the Additive Manufacturing Innovation Growth Field at Evonik. “INFINAM FR 4100L is a perfect example of our commitment to innovation and customer centricity. We believe the unique properties of this product will be well suited for 3D printed prototype and functional production parts in the most demanding aerospace, automotive, and other industrial applications,” says Stoerkle.

The launch of INFINAM FR 4100L underscores Evonik’s leadership in additive manufacturing and its commitment to advancing 3D printing as a large-scale industrial manufacturing technology. Participation in the AMUG 2024 conference will provide Evonik with the opportunity to showcase this and other innovative 3D printing products to a broad professional audience, further promoting technology development and adoption.
