Opel is in the news almost weekly for financial reasons. But the German-based subsidiary of General Motors is also making some technical news. Opel joined with Recaro, a Tier II seat maker, and BASF to develop an all plastic car seat that eliminates the requirement for a steel frame.
The seats are low weight while offering high mechanical strength, good ergonomic properties and a sporty look. The seat pan is made of Ultramid B3ZG8, a very tough yet stiff PA6. Ultramid B3G10 SI is used in the large, free-standing backrest shell as well as in the crossbar. The insert for the backrest shell is made of Neopolen P 9225 K (EPP), an energy-absorbing foam that also covers edges and serves as a module carrier for motors and seat components such as the spinal column support.
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.
