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.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
