<P>PROBLEM TO BE SOLVED: To improve a method for laminated production of a three-dimensional object by preventing deposition of a vapor generating during production of the above object on a hypersensitive member such as a lens. <P>SOLUTION: There is provided a device for laminated production of the three-dimensional object including a construction chamber 19. The construction chamber 19 comprises a height-adjustable construction platform 6; an apparatus 7 for dispensing on the platform, a material layer solidifiable by the action of an electromagnetic ray; and an irradiation unit in the place of a layer corresponding to the object. The irradiation unit includes a radiation source 1, a control unit 2, and a lens 8 present in the radiation path of the electromagnetic ray, and has at least one deposition surface present inside or outside the construction chamber. <P>COPYRIGHT: (C)2013,JPO&INPIT |
