Polyhedron splitting algorithm for 3D layer generation

Abstract

RP(Rapid Prototyping) is often called as Layered Manufacturing because of layer by layer building strategy. Layer building strategy is classified into two methodologies. One is based on the 2D layer and the other is based on the 3D layer. 2D layer is simply created by the intersection between the polyhedron and a slicing plane whereas 3D layer is created with some constraints such as cuttability and manufacturability. We propose a geometric algorithm that uses the feature of individual triangle to create 3D layers.
