ExOne Company Awarded Contract to Develop Binder Jet Manufacturing for Novel Steel Alloy

Strategic Insights -

The ExOne Company, a leading global provider of industrial sand and metal 3D printers, has been awarded a contract by the National Center for Defense Manufacturing and Machining (NCDMM) to develop and qualify binder jet manufacturing processes for AF-9628, a high-strength steel alloy developed by the United States Air Force Research Laboratory (AFRL). This contract aims to explore the possibility of manufacturing parts with AF-9628 using binder jet 3D printing, a technology that has the potential to reduce production costs while maintaining strength and functionality. AF-9628 is currently manufactured using traditional and additive methods, including laser powder bed fusion. The Air Force reports that parts additively manufactured with AF-9628 are about 20 percent stronger than conventional AM alloys.
