If you have ever experienced a tacky mess when trying to bond laminates under high temperatures, Stevens Urethane has a solution with its new "super-high-melt" polyether thermoplastic polyurethane (TPU). Stevens ST-1665 is said to provide one of the highest melt temperatures available in a thin urethane film, between 190 and 210C. Because it requires a higher than usual temperature to become tacky and bond with other materials, its strength and barrier characteristics are not affected by processing temperatures that might melt "normal" urethane films. In multi-layer laminations, the material is typically used on the "high-heat" side of the lamination. The high-melt urethane maintains its integrity and performance properties, while films on the other side of the substrate soften and bond, forming a multi-layer lamination.

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.
