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.

Abstract: There is provided a manufacturing method of the three-dimensional shaped object, the method being capable of reducing an undesirable phenomenon associated with the contamination of the light transmission window with the fume substance. The manufacturing method according to an embodiment of the present invention is a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming, wherein the irradiation with light beam for the solidified-layer forming is performed by directing the light beam into the chamber through a light transmission window of the chamber, and wherein a gas blow is supplied to the light transmission window by use of a movable gas supply device, the light transmission window having been contaminated with a fume generated upon the formation of the solidified layer.

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 by light beam irradiation, wherein as a platform for the three-dimensional shaped object, a plate laminate body comprising a dummy solidified layer and a base plate for the shaped object is used, and the dummy solidified layer is formed on one of principal surfaces of the base plate, whereas the three-dimensional shaped object is manufactured on the other of the principal surfaces of the base plate.

Abstract: There is provided a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming by an irradiation with a light beam in order to provide a selective laser sintering method capable of reducing a warp of the three-dimensional shaped object, the warp being due to a stress around an upper surface of the three-dimensional shaped object. Especially, in the present invention, a part of a region for the formation of the solidified layer is not irradiated with the light beam to form a non-irradiated portion, thereby providing at least one slit-groove at an upper surface of the three-dimensional shaped object, the slit-groove being for reducing a stress of the three-dimensional shaped object.
