Abstract:
A stereolithographic 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 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 a plurality of exposure vectors representing 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 providing a plurality of non-exposure vectors between at least some pairs of successive exposure vectors, wherein the non-exposure vectors comprise a ramp vector and a jump vector.
