Abstract
Systems for and methods of generating three-dimensional objects from a medium capable of selective physical transformation upon exposure to synergistic stimulation, whereby sheets of medium corresponding to cross-sectional layers of the three-dimensional object are dispensed from a source, the dispensed sheets then being selectively exposed to synergistic stimulation thereby forming a layer of the three-dimensional object, the areas not exposed to synergistic stimulation being removed, and whereby successive sheets corresponding to successive cross-sectional layers are dispensed and selectively exposed to synergistic stimulation and integrated together with preceding layers to provide substantially a layer by layer buildup of the three-dimensional object, thereby forming the three-dimensional object.
