Evonik Develops Infinam FR 4100L 3D Printing Resin for Manufacturing Tough, Ductile, Flame-Retardant Parts

Evonik’s Infinam FR 4100L is a photopolymer resin that is both flame retardant and mechanically durable when cured. Designed for use with digital light processing (DLP) 3D printers, Infinam FR 4100L is pourable at room temperature and can be printed and further processed to achieve a desired surface feel.

“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.”

Infinam FR 4100L has a certified UL 94 flame retardancy rating of V-0 at 3-mm thickness. Once cured, the resulting product features high elongation at break, good haptics and an excellent surface finish that can be further machined and polished. It also exhibits a level of toughness similar to materials made of acrylonitrile butadiene styrene (ABS) plastic.

“Evonik is committed to developing innovative solutions that meet the needs of our customers,” says Dominic Stoerkle, head of Evonik’s Additive Manufacturing Innovation Growth Field. “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.”

Evonik’s activities to support 3D printing technology are consolidated under the company's Additive Manufacturing Innovation Growth Field. The strategic goal is to develop and produce industrial, high-performance materials that are ready to use for all major polymer-based 3D printing technologies. As a result, the specialty chemicals company is advancing 3D printing as a large-scale industrial manufacturing technology across the entire value chain.
