Abstract: In this invention, a copper powder to which phosphorus (P) is added is developed such that a high-density laminated and shaped product can be obtained by a laminating and shaping method using a fiber laser as a heat source by appropriately reducing the electrical conductivity of copper, so a laminated and shaped product having a high density and a high electrical conductivity can be obtained. This invention is a copper powder for lamination shaping in which a phosphorus element is added to pure copper. The copper powder desirably contains 0.01 wt % or more of the phosphorus element. The copper powder more desirably contains 0.04 wt % or more of the phosphorus element. The copper powder desirably contains 0.30 wt % or less of the phosphorus element. The copper powder more desirably contains 0.24 wt % or less of the phosphorus element. No element other than the phosphorus element is desirably added to the copper powder.

Abstract: A three-dimensional deposition method and a three-dimensional object are provided. Included are: a step of supplying a powder toward an outer peripheral surface of a shaft, irradiating the powder with a laser beam, and sintering or melting and solidifying at least a part of the powder irradiated with the laser beam to form a formed layer, so as to form a three-dimensional object body in which an internal space communicates with an exterior through an opening; a step of discharging a residue such as the powder in the internal space from the opening to an exterior; and a step of emitting the laser beam toward an end surface of the opening to melt and solidify the formed layer, so as to close the opening.
