Abstract
A manufacturing method of a three-dimensional shaped object includes a first step of depositing powder to form a powder layer, and a second step of scanning and irradiating an energy beam to the powder layer to melt and then solidifying the powder layer to form a solidified layer. The energy beam is irradiated to the powder layer corresponding to a contour area and an inner-solid area inside of the contour area. The first and second steps are alternately and repeatedly executed. The energy beam is scanned such that an irradiation starting point of the energy beam for forming an upper solidified layer does not overlap with an irradiation starting point of the energy beam for forming a lower solidified layer in a view from a lamination direction.
