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.”
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
