Abstract: To manufacture a sprue-bush which is capable of suitably cooling a melt raw resin in a raw resin-flow path as a whole, there is provided a method for manufacturing a sprue-bush, wherein a shaped part is located on a base part to manufacture the sprue-bush, the base part comprising a raw resin-flow path and a cooling medium-flow path, wherein, in the shaped part, a downstream raw resin-flow path portion is located and a downstream cooling medium-flow path portion is also located, the downstream raw resin-flow path portion corresponding to a downstream side region of a raw resin-flow path of the sprue-bush, the downstream cooling medium-flow path portion being positioned around the downstream raw resin-flow path portion and corresponding to a downstream side region of a cooling medium-flow path of the sprue-bush, and wherein the downstream cooling medium-flow path portion is located to surround the downstream raw resin-flow path portion.

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.

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.
