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.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
