Abstract
A three-dimensional shaping method includes a step of forming a powder layer and a step of sintering the powder layer by a moving laser beam or electron beam are alternately repeated to perform a multilayer operation within a container, a plurality of equal-width divided regions are set in a multilayer region along a height direction, and then the number of multilayers N in each of equal-width divided regions which can reflect the degree of variations, according to the degree of variations in the shape of the cross section of a boundary on the upper side and the shape of the cross section of a boundary on the lower side in each of the equal-width divided regions, and the thickness of each multilayer unit in each equal-width divided region is selected, and the coordinates of an outer periphery in each of the cross sections of the number N are set.
