Abstract: Three dimensional shaped object manufacturing method, which is capable of making a life time of a machining tool longer when machining of the surface of a solidified layer is performed using the machining tool. The method includes an alternate repetition of forming a powder-layer and a solidified-layer. The repetition includes: forming a solidified layer by irradiating a predetermined portion of a powder layer with a light beam, thereby allowing a sintering of the powder in the predetermined portion or a melting and subsequent solidification of the powder; and forming another solidified layer by forming a new powder layer on the formed solidified layer, followed by irradiation of a predetermined portion of the newly formed powder layer with the light beam. A surface of the solidified layer is subjected to a machining process, and the machining process is performed on a basis of a condition of an ultrasonic vibration.
