Stereolithography using different types of vector scanning

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, manipulatin...

Zusammenfassung:	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.
