Three advanced plastics welding processes are used in a novel fuel cell based on electroconducting polymer and transition metals in an effort to avoid use of adhesives. “We are using orbital vibration to weld the different membranes (anode and cathode) producing the energy,” comments Didier Perret, sales manager of Branson Ultrasonics in Switzerland. “We are using advanced ultrasonic welding for several assembly operations (to replaces screw, glue or others). And finally we use the latest infrared laser technology GEN 3 to weld the fuel tank with a high safety level.”
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
The first ASME Additive Manufacturing + 3D Printing Conference (AM3D) will be co-located with the organization's International Design and Engineering Technical Conferences (IDETC) and Computers & Information in Engineering Conference (CIE), Aug 2-5 in Boston.
