The key to a new Hewlett-Packard high speed printer is a very intricate injection molded ceramic part. As part of a $1.4 billion, five-year research project, HP design engineers approached a British ceramics company, called Morgan Advanced Ceramics, and asked if it could develop a piece that features 3,900 print nozzles. HP eyed ceramic because of its strength and hardness. Until recent years, ceramic was never a top choice for intricate, small parts because of the poor flowability of common ceramic compositions, and the expense of secondary machining. Morgan is now in full production of the component, which is part of a built-from-the-ground-up piece that rapidly distributes ink to paper, allowing full-color prints in 14 seconds.
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.
