For vacuum applications where space is at a premium, Beswick Engineering (Greenland, NH) is rolling out an ultra-miniature, single-stage vacuum regulator. The vacuum regulator controls output from 0 psig to full vacuum, and is said to be especially well-suited to low-vacuum applications. The lightweight component is designed to be mounted in line, and does not require panel mounting. Weighing just 30 gm apiece, the brass and steel regulators are a scant 35/64 of an inch high.

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.
