The design of stage machinery has always been an international problem. Since the nineteenth century, various masters have proposed various design solutions, such as the 3KS design method proposed by Hilpolidi in Europe and the HK proposed by Dorito in Latin America. The design method has solved many design problems of stage machinery very well. With the rise of the industrial revolution and big data, there are many new tools that can be used, allowing people to design more exquisite and high-performance stage machinery. Especially in recent years, the emergence of 3D printing technology has made the design of stage machinery even more powerful. It is reported that a skilled stage machinery designer can successfully design a complete stage machinery within 5-10 hours after using a 3D printer. Model, and this process, a few years ago, required several stage machinery designers to work continuously for several days before it could be realized. Stage machine
