PROBLEM TO BE SOLVED: To make the amount of light energy to be emitted to a photo-setting liquid uniform. SOLUTION: When one of the sections obtained by slicing a desired shape into plural layers is formed, a radiation, point deciding means 34 decides a single or plural radiation points to which a light is emitted for setting the section based on the shape data of the section. Further optical apparatuses 6, 8, 10 arranged between a light source and a photo-setting liquid are regulated so that the light is emitted from the light source to one of the emission points. After regulating the optical apparatuses 6, 8, 10, the light is emitted to the one emission point and then is emitted to all of the radiation points for light shaping. |
