| Abstract: | Slicing represents an important step in all rapid prototyping processes. This paper proposes the use of critical points for adaptive local slicing for strataconception in particular and rapid prototyping technologies in general. The context of using critical points in rapid prototyping to optimise usual slicing is presented. Its definition on both surfaces and triangular meshings is given and extended to other geometric entities, such as edges, facets and faces. Finally, this new slicing approach is compared with the usual one on a few models manufactured through the stratoconception process. |
