The Research on Slices' Data Repair and Filling Path Optimization

摘要

Fused deposition modeling (FDM) is one of rapid prototyping process, which process includes Common Layer Interface (CLI) file generation and rapid prototyping. This paper focuses on algorithm to repair error datum of slices to generate CLI file and arithmetic-zoning scanning algorithm based intersection sorting which were used to FDM process. Conclusions of experiment show that the algorithm to repair error datum of slices can correct repair the error datum and fast extraction of contour information, and it provides an efficient method for generating CLI file from Stereo lithography (STL) slices; that arithmetic-zoning scanning method can reduce the possibility of model wrapping and shrinkage stress. The two algorithms improve production efficiency of FDM and are worth promoting.
