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.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
