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 including a power adjustment device;specifying a desired power level for the beam of prescribed stimulation;sensing the power of the beam of prescribed stimulation by directing the beam temporarily onto a sensor;sending a control signal to the power adjustment device based on the desired power level and on sensing the actual power of the beam;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.
