A sign of the growing interest in additive manufacturing (3D printing) for making robot grippers is the development of a polypropylene powder specifically for that purpose. New Luvosint 65-8824 comes from Germany's Lehmann & Voss & Co., which has a U.S. branch (Lehvoss North America) in Pawcatuck, Conn. It was developed in collaboration with LMD Innovation, a German producer of robot grippers, which has used 3D printing to make them for a decade (lmd-innovation.de). It also uses Lehmann & Voss's Luvosint X92A-1 TPU powder for laser sintering of flexible parts. The accompanying photo shows a gripper from LMD that uses both materials.
