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.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
