Wittenstein's The alpha V-Drive servo
worm gearboxes have been updated with new features and added torque. The
VDS (shaft output) and VDH (hollow output) gearhead versions have
stainless-steel interfaces to provide service life in washdown applications.
Accessories for these models are also available in stainless steel. The
V-Drive washdown version is food-grade lubrication. This option allows the
V-Drive to be used in the food and packaging industry while maintaining torque
capacity at 100 percent. The lubrication is NSF certified with a protection
category of IP 65.
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.
