Abstract

A system and method of constructing an object layer by layer by applying a material in a liquid state to a first layer, selectively curing to a solid state pre-defined areas of the first layer, where such areas match the coordinates of the object in such layer, and leaving in an uncured state, areas of the layer that are not included in the object in such layer. The uncured areas of the layer that surround the cured areas are cooled and hardened to provide support for the object as it is being constructed. The uncured supporting material in the layer may be removed when the construction of the object is completed.
