An object is to provide a configuration in which, in a three-dimensional shaping method, the thickness of each multilayer unit is appropriately set according to the degree of variation in the cross section of a shaped object in a horizontal direction along a height direction. [Solution Means] In order to achieve the above object, a three-dimensional shaping method is provided in which a step of forming a powder layer and a step of sintering the powder layer by the application of a moving laser beam or a moving electron beam are alternately repeated to perform a multilayer operation within a container, where a plurality of equal-width divided regions 2 are set in a multilayer region 4 along a height direction, and then the number of multilayers N in each of equal-width divided regions 2 which can reflect the degree of variations, according to the degree of variations in the shape of the cross section 3 of a boundary on the upper side and the shape of the cross section 3 of a boundary on the lower side in each of the equal-width divided regions 2, and furthermore, the thickness of each multilayer unit in each of the equal-width divided regions 2 is selected, and moreover the coordinates of an outer periphery 6 in each of the cross sections 3 of the number N are set. |
