Research on Physical Model making of Mining method based on 3D Printing Technology
Abstract:It is such a complex process to build up a traditional physical model of mining method, with some obvious defects: long cycle, high cost, and high professional technical requirements, which greatly limits the promotion of mining physical models. As a new manufacturing technology for realizing the 3D virtual model materialization, 3D printing technology has the advantages of high flexibility, low manufacturing cost, and short cycle. This paper studies the physical modeling of mining method based on 3D print technology, and establishes the standardization process of mining method modeling based on 3D print technology: 3D modeling , model modification , printout , assembly forming and post-processing. Analyzing the key technologies such as engineering structure display, structural stability, and model best scale based on 3D print technology mining model, and put forward the concepts of the Yin-mold, Yang-mold and Yin-yang mold. The rapid build-up process of the physical simulation model of the mining method is achieved by combining the Yin-mold, Yang-mold and the Yin-yang model, cutting, presetting the connection structure and determining the optimal output size. The research provides a new and reliable mean of realizing the complex and variable mining method model.
