Abstract
A method of metallic part fabrication includes loose metal powder spread over an additive manufacturing build tank. A fluid binder/ceramic agent solution is selectively deposited upon a predetermined portion of the loose metal powder to create a printed layer. The printed layer is dried to remove a portion of the fluid binder/ceramic agent solution from the printed layer, to create a dried layer. A plurality of dried layers is stacked longitudinally to create a green part. The green part is bulk sintered to create a metallic part with uniformly dispersed and distributed ceramic particles in the metal matrix. A system for metallic part fabrication is also provided.
