Abstract:
A method of forming a three-dimensional object from a plurality of adhered laminae by exposing successive layers of a material to a beam of prescribed stimulation, comprising:providing a controllable source of a beam of prescribed stimulation;forming a layer of material adjacent to any last formed layer of material in preparation for forming a subsequent lamina of the object;exposing the material to the beam of prescribed stimulation to form the subsequent lamina of the object according to vector data descriptive of the subsequent lamina; andrepeating the acts of forming and exposing a plurality of times in order to form the object from a plurality of adhered laminae,wherein the source of prescribed stimulation is controlled to provide one quantity of prescribed stimulation in the beam when exposing the material according to a first set of exposure vectors and another quantity of prescribed stimulation when exposing the material to a second set of exposure vectors.
