Optimization and application of STL model slicing algorithm in rapid prototyping

The stratification of STL files model is an important link of rapid prototyping systems. In order to improve the efficiency of layered, this paper puts forward a layered optimization algorithm: According to the triangle mesh generation's two axis coordinates, we can group and sort from small to large, then get the line intersection on these triangular mesh, and output section contour line and data in turn. This algorithm can not only save time, but also improve the layered efficiency, because it is not necessary to establish topology relation of the triangle mesh and to deal with the connection relationship of delivery line. Through analysis of the turtle and bucket teeth model stratified, the practicality and high efficiency of the proposed algorithm is verified.
