摘要： A system may produce a desired three dimensional object that includes a tank that holds a liquid that solidifies upon exposure to light; a controllable stage that controllably moves within the tank; a controllable light source that emits a light image in a controllable pattern; and a controller that controls the controllable stage and the controllable light source so as to cause at least three cascaded layers to be sequentially solidified in the liquid that collectively approximate at least a section of the desired three dimensional object and that collectively form at least one up-facing step at their outer edges; and, following the solidification of the at least three cascaded layers, cause a meniscus of the liquid to form and solidify in the at least one up-facing step. The controller may control the number and/or width of the sequentially solidified cascaded layers.
