In certain applications, a cylinder's cycle time is critical. That means that it must not only extend quickly; it must return fast, as well. Using poppet-type Jumbo Exhaust Valves from Clippard Instrument Laboratory, machine builders can speed the return, even on pneumatic cylinders with long strokes. To accomplish that, the Jumbo Exhaust valve mounts on the cylinder, and dumps pressure on the other side of the piston as soon as the inlet pressure reaches zero. The Jumbo Exhaust Valve allows for use of smaller control valves and longer supply lines. It is said to be ideal for packaging machinery and automation applications.

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.
