Application and Prospect of 3D Printing Technology in Rail Transit Parts
With the rapid development of rail transit industry,the complex castings are demanding.Rapid repair of vul-nerable parts such as train wheels and rails cannot be completed,and the existing storage mode cannot meet the rapid replacement of rail transit parts.As an emerging manufacturing technology,3D printing technology has the advantages of rapid manufacture,high quality and wide application.However,the application in rail transit parts is rarely devel-oped.The research progress on 3D printing technology in the casting and development of complex parts of rail transit,the rapid repair of wear-prone parts such as rails,wheels and axles,as well as the efficient maintenance and replace-ment of rail transit parts were summarized,and the exsiting problems and application directions of 3D printing technol-ogy in rail transit parts were prospected.
