The ExOne Co., a manufacturer of industrial sand and metal 3D printers, has announced the qualification of 15 new metal, ceramic and composite materials for its family of binder jetting 3D printers. The additions add up to a total of 21 qualified printable materials: 10 single-alloy metals, six ceramics and five composites. 

The company’s binder jetting technology is designed to manufacture dense and functional precision parts at high speeds by depositing a liquid binder onto each layer of powder. 

“ExOne continues to make aggressive and outstanding progress in qualifying new materials for 3D printing on our machines,” says CEO John Hartner. “Qualifying a new material for binder jet 3D printing is complex work that involves optimizing how materials, machines and processes work together. We would like to thank our customers and partners for their assistance in accelerating this important work, which is enabling more sustainable manufacturing and part designs.” Those partners have included Global Tungsten & Powders, H.C. Starck Solutions, NASA, Oak Ridge National Laboratory, SGL Carbon, the U.S. Army, the U.S. Department of Energy, the University of Texas at El Paso and Virginia Tech.
