There’s a cool new backlighting technology on display at the 63rd International Motor Show (IAA) in Frankfurt, Germany. The instrument luster on BMW’s new 5-series features inverse forming technology for three-dimensional black panel film that has no distorted effects. In conventional thermoforming, thinning occurs at certain places on the film causing polarization in these areas in the form of rainbow-like distortions known as Newton’s rings. Achim Hosenfeld, vice president electronics at Johnson Controls, says: “Unlike before, the film is placed down into the forming tool. The result is a special embossed surface structure that is imprinted by the texture of the tool. This eliminates the need for an expensive anti-reflective coating and also makes the display easy to read.”
The black 3D film produces a smooth transition between the flat printed surfaces of the analog instruments and the digital information display.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
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.
