The R256 single-axis controller and driver is engineered to feature the same compact size as its predecessor, yet is capable of increased microstepping resolution and higher output current. It is capable of step resolutions ranging from 2× to 256×, and it operates from +12 to 20V dc. Its phase current ranges from 0.1 to 2A peak. It is designed to be programmed via serial port and used as a stand-alone unit with no PC connection required.
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.
