The softest thermoplastic elastomers—those measured on the Shore 00 scale—haven't traditionally been easy to turn into finished products. Now GLS Corporation (www.glscorp.com) has come up with the Versaflex CL2003, which features hardness of just 30 Shore 00. Yet the material, which comes as free-flowing pellets, can be injection molded into finished components or overmolded onto other substrates. Samples of the material exhibit both a water-clear complexion and a non-oily feel.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
