Timex watches aren't the only devices built to take a licking. Recently, a Fluke ScopeMeter was put through its paces by some hapless thieves and some wary emergency workers. The equipment was stolen from a locked car owned by electrician Brian Cheney who was taking a training class at Kawasaki's Lincoln, NE plant. During the ensuing police chase, the perps threw the case, with scope inside, out the window. Mystified, the cops had the fire department x-ray the case. After identifying wires and "some type of electrical-looking equipment," the fire department exercised caution by blowing the whole thing open with an explodable dart and then dousing the contents with water. For good measure, they then cut all the leads on the waterlogged scope, which the dart dinged but didn't penetrate. When Kawasaki electricians took the scope back to the shop, and drained and dried it, they discovered it was fully operational.
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.
