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.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
