1. A shaping method to form a three-dimensional shaped object by using a Directed Energy Deposition (DED)-type shaping system that has a beam irradiation section which emits a beam, a material supply section which supplies shaping material to an area irradiated with the beam by the beam irradiation section and a movement system having a movable member, the method comprising:
placing a workpiece on the movable member;
measuring position information of a target surface of the workpiece on the movable member; and
applying shaping to a target portion on the target surface by the DED-type shaping system, based on 3D data of a three-dimensional shaped object to be formed on the target surface and the position information of the target surface that has been measured,
wherein after placing the workpiece on the movable member and before applying any shaping for the workpiece by forming a molten pool on the target surface with the beam, the position information of the target surface, on which a first shaping is to be applied, of the workpiece is measured, and then the first shaping by forming the molten pool on the target surface with the beam is performed based on the 3D data and the position information of the target surface measured before applying any of the shaping.
