The US Patent office yesterday granted Apple Computer a patent for a process called double back injection molding used to make electronic housings. The process allows the distinctive glowing border effect in Microsoft's Zune player . The process allows creation of two different color effects as well as improved structural characteristics of the border wall. it avoids expensive and complicated action in tools. Apple uses double shot injection molding for both iPods and iMac desktop computers, which have a clear shell over a black or white layer. “The two shot injection process allows for a thinner walled enclosure that uses less materials and allows for added structural features that would not be possible using traditional molding techniques,” according to the patent summary. It was not clear, but seemed apparent, that Microsoft may have to pay a licensing fee to continue use of the process. One blogger stated, without documentation, that Apple was stealing Microsoft’s idea. Apple was not available for comment.
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.
