Made in China 2025 I energy saving and new energy vehicles put forward higher requirements on connection technology from the aspects of better quality and efficiency in body manufacturing. With the development of Industry 4.0, China’s automobile industry and the world’s automobile manufacturing industry have gone through roughly four similar stages. With the acceleration of transformation and restructuring, the development of energy-saving and new-energy vehicles is an important way to solve energy and environmental problems. Automobile products have been transformed to light weight, production and manufacturing methods have been transformed to mass customization, new energy technologies have been developing at a faster pace, and automobile manufacturing has become increasingly digitalized and modular. Combined with this new situation, this paper expounds the application status of 3D printing technology in China’s automobile industry in detail, and makes a brief analysis and prospect of its prospect[1].

The Ministry of Education's "Excellent Engineer Education and Training Program" is a major measure to promote China's engineering education powers to engineering education powers. The program aims to cultivate a large number of high-quality engineers and technicians with high innovation ability and adapt to the needs of economic and social development, and to serve the country in the path of new industrialization development, building an innovative country and strengthening the country. In combination with the talent training model of excellent engineers, it is proposed to adopt the application-oriented engineer training mode, that is, adopt the "3+1" mode, three years of internship in the school, and one year of study in the enterprise and graduation design. As a teaching-oriented institution, the target orientation of engineering talent training should be emphasized and applied, laying a solid foundation for the next step of engineering master training. In view of the existing problems in the training model of automobile service engineering talents, the research and reform of the training program for automotive service engineering professionals is carried out in response to the requirements of the excellent engineer training program, so that it can better adapt to the requirements of cultivating high-quality engineers.

With the rapid development of 3D printing technology, it has been applied in more and more fields and products, so the research on 3D printing technology control process has important practical significance. This paper first analyzes the current development of 3D printing technology, and then introduces the classification of 3D printing technology, as well as the classification of control process system. Finally, several control process systems of 3D printing technology are analyzed and studied.
