Abstract
There is provided a manufacturing method of a three-dimensional shaped object, the method being capable of reducing a warp deformation of the three-dimensional shaped object. The manufacturing method according to an embodiment of the present invention produces a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming on a base plate, wherein the forming of at least one prior solidified layer is performed under a higher temperature condition than that for the forming of a subsequent solidified layer, the at least one prior solidified layer being formed prior to the subsequent solidified layer.
