The ExOne Company announced that 15 new metal, ceramic and composite materials have been qualified by ExOne and its customers for 3D printing on the company’s family of metal 3D printers.

With these additions, owners of ExOne metal 3D printers can now print 21 qualified materials: 10 single-alloy metals, six ceramics, and five composite materials. More than 24 additional powders have been qualified for 3D printing in controlled research and development environments, including aluminum and Inconel 718.

ExOne’s exclusive binder jetting technology transforms powdered materials into dense and functional precision parts at high speeds. Binder jetting is a method of 3D printing in which an industrial printhead deposits a liquid binder onto a thin layer of powdered particles, layer by layer, until the object is formed.

Partners that have assisted ExOne in qualifying materials include 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. In all, ExOne customers are now 3D printing more than a dozen different materials for R&D, prototypes, and production, including proprietary materials.
