(Desktop Metal: Burlington, MA) -- Desktop Metal has announced three new metals for use in its binder jet 3D printers, partnering with three separate organizations to test and verify the results.

Copper alloy C18150 was developed and provided by Sandvik Osprey, a unit of Sandvik Additive Manufacturing and tested by a top-five global automotive manufacturer. It’s rated for use on two single-pass jetting (SPJ) models—the P-1 for research and development of binder jetting projects for serial production; and the P-50, a production metal binder jet system.

Sandvik says its C18150 powder routinely delivered as-sintered densities of 98–99 percent when printed on the P-1, allowing for unique part design targeted for high-volume production. Chromium zirconium copper has strength, conductivity, and corrosion resistance, and withstands service temperatures up to 500˚C.

Desktop Metal worked with Detroit-based automotive supplier TriTech Titanium Parts to qualify Ti64 alloy for binder jet 3D printing.
