A photo-sodification modeling apparatus is provided. The apparatus comprises: a container, a holding plate, a lifting mechanism, a light source module, and a control unit. The container provides an accommodation space for accommodating a light-curable material, and includes: a base plate and a wall structure. The base plate is transparent or translucent. The wall structure is disposed around the base plate. The lifting mechanism is used for moving the holding plate. The light source module is disposed under the container. During formation of a solidified layer of a three-dimensional object, the base plate provides an electric or magnetic field so that the light-curable material in the container will not solidify on a surface of the base plate, thus resulting in the solidified layer having a reduced viscosity when the solidified layer is closer to the surface of the base plate.
