Improved performance at the system level results from improvements in one or all of the subassemblies in the system. Completing the design could mean adding a right-angle gearhead, an incremental encoder or a controller. Improved performance could come from lower-backlash in the gearhead, higher resolution from the encoder, or the ability to control up to six motion axes. Here are examples in each of these areas.
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.
