Abstract
A method of forming a part includes metal binder jet printing a first green component with a first attachment interface, de-powdering the first green component, assembling the first green component with a second component comprising a second attachment interface and forming an assembly such that the first attachment interface and the second attachment interface are adjacent to each other. The assembly is sintered such that volumetric shrinkage of at least the first green component creates a compressive force across the first attachment interface and the second attachment interface, and the compressive force across the first attachment interface and the second attachment interface and heat from the sintering results in a metallurgical bond across the first attachment interface and the second attachment interface such that a monolithic part is formed.
