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; 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 reduce or completely stop the source of prescribed stimulation so as to reduce or stop the output power during production of the prescribed stimulation, while forming the object, for at least a portion of at least one period of time when the prescribed stimulation is not needed for exposing the material.
