Additive manufacturing — a new vector in the production and repair of rolling stock

The influence of the fourth industrial revolution, known as Industry 4.0, on modern industrial production and social life is analyzed. The main advantages of Industry 4.0 are presented, such as increasing productivity and occupational safety, developing new products and materials, as well as increasing the competitiveness of products. Special attention is paid to additive technologies and their role in modern engineering within the framework of the Industry 4.0 concept. The methods of additive technologies, their classification by materials and production methods, as well as their various applications in various industries are described in detail. An example of the successful use of additive technologies is presented on the example of JSC Uralvagonzavod Scientific and Production Corporation, where molds and rods for casting parts with high speed and quality are created using 3D printers. The project of introducing 3D printers into the service depots of the directorate of motor car rolling stock of JSC Russian Railways is considered, with an emphasis on the economic and temporary benefits from the use of additive technologies. The concept of introducing additive technologies in the maintenance and repair of rolling stock involves the creation of support depots on the railway network of JSC Russian Railways. In conclusion, the importance of training highly qualified specialists in the field of additive technologies and the need to develop educational programs to train future employees capable of solving complex tasks of creating and applying new industrial technologies is presented. Special attention is paid to synergetic approaches in education to combine learning with scientific activity and the creation of innovative technological solutions.
