[Abstract]:3D printing technology is a new technology which integrates information technology, mechanical engineering and material science. It has been widely used in every aspect of our daily life. From the point of view of computer technology, the key technology of 3D printing is the data processing of 3D model. The current 3D printing software can be divided into commercial special software and open source software. The commercial special software is generally expensive and can not be used generally, which is not conducive to the promotion of 3D printing technology and the development of industrialization. Open source software can solve the preprocessing process of 3D printing, but the algorithm is inefficient and can not meet the requirements of specialization. And most of the commonly used 3D printer processing software is completely using the open source software of foreign countries or simply to the interface of Chinese, understanding of the core algorithm is not deep enough, let alone to optimize the algorithm. In order to solve this problem, this paper studies and analyzes the process of 3D print preprocessing software, and divides it into several core module algorithms. A set of 3D print preprocessing software based on STL file is developed to solve some practical problems in the process of data processing. Firstly, the paper introduces the demand of 3D printing software and the development status of 3D printing software at home and abroad. Based on the analysis of 3D printing principle, the paper puts forward the overall scheme of software design, and briefly introduces several core data structures in the software. Secondly, the analysis and design of several core module algorithms of the bottom algorithm of 3D printing software are described in detail. The 3D model is imported, sliced, and supported automatically by using object-oriented programming method. Process path planning and GCode generation functions. Then the software interface is developed by using the DEV-C development environment and the OpenGL graphic interface, which realizes the setting of 3D printing parameters, the geometric transformation of the model and the switching between different display modes. Finally, the GCode generated by the software is used to print the 3D printer, and the results of the software are tested and verified. The experimental results show that the algorithm is accurate and feasible, the slicing efficiency is high, the supporting structure is reasonable and there is no omission. The designed software can meet the requirements of 3D printer in function.
