This morning’s newspapers are full of stories of deep budgets that are sure to affect funds for scientific research. And buried deep inside is a story of a call by leading American scientists to research and develop new sources for energy-critical materials, such as lithium and tellurium.
There are two issues. Demand is rising for these materials to produce lighter weight vehicles, batteries for electric cars, thin film solar cells, and a variety of other emerging energy-related applications. At the same time, the largest known source of these materials, China, is taking steps to shut off the spigot.
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.
