Metal injection molded components are used in the Eurofighter Typhoon as part of a strategy to reduce costs without compromising performance. A validation study on MIM was conducted by Pratt & Whiney and MTU Aero Engines of Germany with promising results. MIM components will be used in the EJ200 engine in the Eurofighter.. Blades and vanes in the turbine have usually been cast but MTU says the new MIM vanes combine the cost advantage of cast metal with the strength of forged metal. The MIM parts achieve 95% of the strength of forged parts. The power of the engine makes it a key combat aircraft for NATO forces,
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.
