    摘要： This invention relates to the stepwise layer-by-layer formation of a three-dimensional object through application of the principles of stereolithography and to the automatic detection of surface features of each layer of a three-dimensional object to manufacture parts more reliably, more accurately and more quickly. Automatic detection of trapped volume regions and size of solidified cross-sectional regions are disclosed. Automatic selection of recoating styles is made based on (1) the detected regions,(2) empirically or otherwise determined optimum recoating styles for different types of regions, and (3) a look-up table, other correlation system, or processor for associating recoating style information with laminae containing particular identified regions.

    摘要： Apparatus for and related methods of forming three-dimensional objects out of a building material, which is normally solid, but which is flowable when heated. In one embodiment, a support material is used to fill in portions of layers which are not to be solidified as part of the object, thus providing support to otherwise unsupported portions of other layers. Advantageously, the support material is also normally solid and flowable when heated, and has a lower melting point than the building material enabling the support material to later be removed without damaging the object. In an alternative embodiment this support material can be used to build a support such as a web support, or the like, for supporting an object surface from a second surface. In another alternative embodiment, such an apparatus is combined with a conventional stereolithographic apparatus to provide means for forming an object out of conventional stereolithographic materials, but utilizing a normally solid but thermally-flowable support material to provide support to the object, either on a layer-by layer basis, or by building supports such as web supports.

    摘要： An improved stereolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to 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.

    摘要： A method and apparatus for eliminating or substantially reducing curling effects in stereolithographically formed objects. Synergistic stimulation is applied to a curable material to form a three dimensional object through the build up of successive layers. Curling between successive layers is eliminated or substantially reduced by curing a balancing layer in relation to a balanced layer such that reverse curl of the balanced layer caused by the balancing layer offsets or negates normal curl of the balanced layer caused by the balancing layer.

    摘要： A stereolithographic method for constructing an object from a medium capable of solidification upon exposure to synergistic stimulation (e.g. a laser beam). Stacked layers of solidified medium are constructed by exposing the medium to synergistic stimulation in magnitude and pre-selected pattern, such that each layer is formed with external boundaries and up and down facing surfaces as necessary. At least a portion of a layer which is neither upfacing nor downfacing is also skinned, e.g., provided with a continuous skin formed by overlapping skin vectors or traces of the laser beam. Alternatively, all intermediate or internal cross-sectional layers are provided with skin and cross-hatch. Upfacing and downfacing features, and intermediate layers may be provided with a skin created by scanning in a first pass using non-consecutive skin vectors followed by scanning in at least one additional pass that completes the exposing process by filling in between the originally drawn vectors. To reduce waffling, regions of intersecting vectors at least in down-facing surfaces are determined. Exposure of one or more of the respective intersecting vectors is reduced at the regions of intersection to provide downfacing features with a uniform exposure.
