Abstract
A three-dimensional object shaping method includes the steps of a powder layer forming step, a sliding step of a squeegee on the supplied powder, and a sintering step of irradiating the powder layer, all successively repeated, wherein after dividing shaping regions into a plurality of laminating units, each laminating unit of the plurality of laminating units is divided into an inside region including a maximum prearranged sintering region, and an outside region not including the maximum prearranged sintering region, and wherein the squeegee sliding speed in the outside region is set to be greater than the sliding speed in the inside region.
