Designed for the ever-changing automotive industry, these filters use multi-layer filter media, also known as "fleece," made from melt-blown superfine fibers with a compressed cellulose substrate layer, a filter system already used by Mercedez-Benz as the world's first fleece oil filter, and as a fleece air filter in the Audi A8. The filter can improve current filtration standards from 85-99 percent to 95-99.9 percent, with ultra-small particles measuring between three and five microns.
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.
