NORTH HUNTINGDON, Pa.–(BUSINESS WIRE)–The ExOne Company (Nasdaq: XONE), today announced a new clean-burning metal binder, CleanFuse, that will enable future binder jet 3D printing of premium metals such as aluminum and titanium, which are sensitive to carbon residue left behind by other binding agents during sintering. The patent-pending formula will be available in the first quarter of 2020. While ExOne systems already binder jet more than six qualified metals, including the popular stainless steels 316L, 304L and 17-4PH, a clean-burning binder is a key step in the development of binder jet 3D printing for some other high-demand metals, as well as some ceramics. “CleanFuse is an important advancement for the field of binder jet 3D printing,” said John Hartner, ExOne CEO. “In addition to enabling the future binder jet 3D printing of aluminum and titanium, CleanFuse will also be important for 3D printing some beta materials now moving through our strict qualification process, such as Inconel 718 and 625.” Binder jetting is a mature 3D printing process that uses a digital file to quickly inkjet a binder into a bed of powder particles — metal, sand or ceramic — creatin...
