A new low profile rotary stage leverages Piezo Ceramic Linear Motor (PCLM) technology for use in handling 300-mm silicon wafers for semiconductor processing. With a profile height of only 32 mm, the PLR-300 allows for a minimal working stack-up height when used with other stages--such as mounted atop and straddling a linear stage. This is very beneficial for minimizing causes of abbe error. Powered by two diagonally opposed PCLMs, the PLR-300 is said to provide superior drive balance and intrinsic smoothness. The PCLM also does not generate heat during operation. The stage is non-magnetic as well and compatible with clean room standards. Angular resolution is ±0.0005 degrees with a positioning accuracy of ±2 microns. Anorad, Product Code 4215.
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.
