摘要： A method of forming a three-dimensional object layer-by-layer by selectively exposing a solidifiable fluid medium to a beam of prescribed stimulation capable of satisfying the medium, comprising: providing a surface shape set of data defining the surface shape of the object to be formed, manipulating the surface shape set of data to produce layer data relating to each of successive layers in the formation of the object, and forming each said of successive layer by scanning the fluid medium with said beam of prescribed stimulation in a vector fashion in accordance with the layer data for the layer, wherein the production of layer data for each layer includes the determination of the existence of different regions of a prescribed plurality of region type for scanning the layer in dependence upon the determined region types.

摘要： An improved stereolithography system for generating a three-dimensional object 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, information defining the object being structurally specified to reduce curl, stress and distortion in the ultimately formed object, the 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. A stereolithographic distortion known as curl is defined, and several techniques to eliminate or reduce curl are described, including dashed line, bent line, secondary structure, rivets, and multi-pass techniques. In addition, a quantitative measurement of curl known as the curl factor, and a test part known as a quarter cylinder are described, which together can be used to measure the effectiveness of the above techniques in reducing curl.
