GE Plastics long-standing attack on polyvinyl chloride continues in the Chevy Volt. Flexible Noryl replaces polyvinyl chloride for environmental and weight-saving reasons. Today's cars have over a mile of wiring, which is mostly made with PVC coating. The case against PVC, says GE, is that it contains halogen and releases dioxins when burned. The Noryl coating is also smaller in diameter than the PVC, making it easier for engineers to manipulate wires in the car. The PVC producers have long maintained that PVC is safe when incinerated properly. European regulators have been the most aggressive in attacking the use of PVC.
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.
