PROBLEM TO BE SOLVED: To provide a three-dimensional shaping apparatus and a three-dimensional shaping method which exhibit high shaping accuracy without increasing the costs.SOLUTION: A three-dimensional shaping apparatus projects an image onto an image projection plane which is a boundary plane facing a liquid-state photocurable resin located on a bottom surface of a tank storing the liquid-state photocurable resin, forms a hardened layer corresponding to a predetermined thickness of liquid layer on an undersurface of shaped object holding means which serves as a bed of a three-dimensionally shaped object to be placed in the tank, and raises the shaped object holding means by the predetermined thickness of liquid layer to repeat in sequence the steps of projecting an image onto the image projection plane and forming a new hardened layer to laminate a hardened layer of the photocurable resin to thereby manufacture a three-dimensionally shaped object. The three-dimensional shaping apparatus has a plurality of image projection means each of which projects an image onto a different region of the image projection plane to thereby project a predetermined image onto the image projection plane. |
