Evonik has launched a new photopolymer resin that is both flame retardant and mechanically durable when cured. Designed for use with DLP (digital light processing) 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 3mm 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 ABS (acrylonitrile butadiene styrene) plastic.

"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.
