Verfahren zum Glätten einer stereolithographischen Kontur

An improved slicing technique for stereolithography is disclosed that employs micro-slicing or intermediate slices by identifying intermediate triangle vertices (1, 2, 3) in the STL file data in terms of surface triangles. Intermediate slice layers are passed through each intermediate vertex (1, 2,...

More Information
Summary:An improved slicing technique for stereolithography is disclosed that employs micro-slicing or intermediate slices by identifying intermediate triangle vertices (1, 2, 3) in the STL file data in terms of surface triangles. Intermediate slice layers are passed through each intermediate vertex (1, 2, 3) to create a final build object or part that has smoother contouring, greater accuracy and an improved surface appearance than parts obtained using prior slicing methods.
