Abstract: Since there were different concerns about precision and efficiency of part's manufacturing, various slicing algorithms were developed. According to the different machining precision in the same machining time of these slicing algorithms, they were divided into two kinds, namely uniform layer slicing and the adaptive layer slicing. The studies and development of the uniform layer slicing and the adaptive layer slicing were discussed by analysis of STL model, original Computer Aided Design(CAD) model and point cloud data. And then the principles and study results of some advanced slicing algorithm including sloping slicing and curve surface slicing were introduced. At last, the research trend in slicing method of rapid prototyping was discussed.
