A New Slicing Method for AMF Model with Topology Structure

In this paper, a slicing method for AMF model is proposed. This method combines region growing surface reconstruction with a topology structure slicing method for AMF model. We perform half-edge match in the region growing reconstruction process to obtain the topology structure of the triangular mesh model. Then, the topology relation between adjacent facets is preserved in an AMF file which is extensible, and a slicing process based on these topology information is accomplished. Our method integrates the slicing process of 3D printing with topology structure reconstruction, reducing the deviation brought by step-by-step operations. Compared with the slicing approaches based on STL files, experiments show that our method improves the slicing efficiency without decreasing the accuracy.
