When downed U.S. helicopters in Somalia led to a fierce urban battle for U.S. soldiers in 1993, it prompted the development of a new computer-enabled tool by the Office of Naval Research. This tool doesn't fire rockets, it just tells the soldiers where they are and then augments their view with an overlay of images fed through computer-enabled goggles. If, for example, soldiers become lost in an urban area, a global positioning system provides coordinates to a computer that provides a map and directions for escape routes. "Being able to look at stuff and seeing information in context with that stuff is what it's all about," says Steven Feiner, a Columbia University professor of computer science that is helping develop the tool.

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.
