A system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process.

[ I claim:] [2.] A method of producing a three-dimensional object from a medium capable of solidification when subjected to synergistic stimulation, said method comprising the steps of:a. providing data representing the three-dimensional object;b. providing said medium;c. forming a layer of medium in preparation for forming a lamina of said object, said layer of medium having a surface;d. selectively exposing said surface of said layer of medium to a beam of synergistic stimulation in accordance with said data to form said lamina integral with any previously formed lamina;e. repeating steps (c) and (d) a plurality of times to form said three-dimensional object from a plurality of solidified and adhered laminae; andf. wherein said step of exposing comprises scanning at least a portion of one layer according to a plurality of successively scanned parallel lines wherein the scanning direction of each successively scanned parallel line is antiparallel to the scanning direction of the immediately preceding scanned line in the succession.
