Interested in mechatronics? There are some very cool examples coming out of Germany using a plastics process called “outsert” molding. In outsert molding, plastic pieces are molded into a frame of metal or some other material. Two examples are new infusion pumps made by medical device OEM B. Braun of Germany. The process begins with the creation of a frame for the pump that consists of a chassis, bolt, flap and pump chassis. High-performance plastic parts are molded onto the plate in a one-shot process. The biggest advantages are part reduction (up to two-thirds) and elimination of secondary operations. The Braun parts are made at the TB&C Outsert Center in Herborn, Germany. TB&C’s use of outsert techniques dates to 1985 when its parent, Phillips Metallwaren, was forced by Asian customers to dramatically reduce costs on car auto tape drives. TB&C says reject levels with the process are low at 25 ppm. Electromechanical structures are molded by TB&C for large roof systems, automated teller machines as well as mediacl devices with microtransmission.
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.
