Abstract: A method and apparatus for making a three-dimensional object by solidifying a solidifiable material are shown and described. A photohardening inhibitor is admitted into a surface of a photohardenable material to create a “dead zone” where little or no solidification occurs.

A number of techniques including continuous/discontinuous mode switching, multiple illuminations of portions of the same layer, and the use of gray scaling are disclosed for regulating the size of the dead zone.
