  • Patent number: 11453054
    Abstract: There is provided a method for manufacturing a three-dimensional shaped object by a continuous formation of a plurality of solidified layers through a light beam irradiation, the three-dimensional shaped object being provided with a hollow portion in an interior of the shaped object. The manufacturing method performs the formation of the solidified layer by irradiating a raw material with a light beam at the time of suppling the raw material, thereby allowing a sintering of the raw material or a melting and subsequent solidification of the raw material. In particular, a solidified foundation portion is provided as a part of the three-dimensional shaped object, the solidified foundation portion being used for a platform for a formation of a subsequent layer provided as the solidified layer. An orientation of the solidified foundation portion is changed prior to the formation of the subsequent solidified layer.
