Bombardier, the Canadian transportation company, is taking a close look at new aluminum-lithium alloys for its C-Series Aircraft under development. Under particular study is the 2099 grade for use as extrusions for internal structure and 2199 sheet and plate for fuselages and lower wring applications. The new alloys reduce weight and improve performance of aircraft. The new planes aren’t expected to take flight until 2013. One potential customer is China Aviation Corp., a development partner with Bombardier.
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.
