Application: Additive manufactured object and method of manufacturing additive manufactured object (Patent ID: US20230390869A1)

The patent filed by Mitsubishi Electric Corp. describes an additive manufactured object that consists of a stack with a first metal layer and a second metal layer separated by an intermediate layer. The intermediate layer includes a first structural part made of the first metallic material and a second structural part made of the second metallic material, with the two parts engaging each other in a unit structure. The arrangement of these unit structures in the intermediate layer exhibits translational symmetry in a plane perpendicular to the stacked direction, with an intermetallic compound layer at the junction interface between the first and second structural parts.

Furthermore, the patent details a method for manufacturing this additive object, involving the formation of the intermediate layer on the first metal layer and the arrangement of the second dot beads on the intermediate layer to form the second metal layer. The combination of materials forming the first and second metallic materials results in the creation of an intermetallic compound layer at the junction interface between the first and second structural parts. The method ensures that the first dot bead of the first structural part and the second dot bead of the second structural part are stacked in the stacked direction and are at an identical position in a plane perpendicular to the stacked direction, providing a constant strength between the two structural parts.
