A method of photoforming a three-dimensional object, comprising the steps of transferring onto a work table (11) a semi-hardened layer (14d) of a photohardenable resin separably supported on a base film (14a), photoforming a hardened layer (q) by exposing the semi-hardened layer (14d), the hardened layer (q) being laminated on a previously hardened layer (q) to photoform the three-dimensional object, and when the hardened layer (q) is photoformed, photoforming a first-region hardened layer forming the three-dimensional object and also a second region hardened layer (54) that is adjacent to the first-region hardened layer through a predetermined space, the first-region hardened layer being supported through a portion of the semi-hardened layer (14d) by the second-region hardened layer (54). An apparatus for photoforming a three-dimensional object, comprising transfer means (20) for transferring onto a work table (11) a semi-hardened layer (14d) of a photohardenable resin separably supported on a base film (14a), and irradiation means (15, 16) for photoforming a hardened layer (q) by exposing the semi-hardened layer (14d), the hardened layer (q) being laminated on a previously hardened layer (q) to photoform the three-dimensional object. <IMAGE> |
