Abstract

A method and apparatus for making a three-dimensional object by solidifying a photohardenable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material through a flexible film to create a “dead zone” where little or no solidification occurs. The dead zone prevents the exposed surface of the photohardenable material from solidifying in contact with the film. The inhibitor causes the film to deform along the build axis, thereby creating a non-planar interface between the photohardednable material and the film. A method is provided to compensate the three-dimensional object data based on the deformation of the film.
