Wei Xiangyang) 3D Printing is a kind of rapid prototyping technology. As a disruptive technology, 3D printing technology is changing people’s lives. From simple daily necessities to extremely complex human organs, even sophisticated manned spacecraft and cosmic satellites, 3D printing technology has turned more and more “impossible” into reality. In recent years, my country’s 3D printing field has grown from nothing to precision, and has achieved world-renowned achievements, and the 3D printing industry in our province has been leading the way with its strong scientific research strength and industrial scale. Among them, there is a leading figure who has to mention, he is the academician of the Chinese Academy of Engineering, the doctoral supervisor of Xi’an Jiaotong University, and Professor Lu Bingheng. On August 21, 2015, at the State Council Special Lecture on Advanced Manufacturing and 3D Printing hosted by the Standing Committee of the Political Bureau of the CPC Central Committee and Premier of the State Council Li Keqiang, Lu Bingheng, academician of the Chinese Academy of Engineering and professor of Xi’an Jiaotong University, introduced the status quo of my country’s manufacturing industry and the world’s mainstream 3D printing technology And the major scientific and technological breakthroughs that will be brought about, and put forward relevant suggestions.

Lu Bingheng, born in Bozhou, Anhui in February 1945, is a well-known scientist in the field of China’s machinery manufacturing and automation. He is currently an academician of the Chinese Academy of Engineering, a professor and doctoral tutor at Xi’an Jiaotong University, and the director of the National Engineering Research Center for Rapid Manufacturing. According to common sense, 72 years old should be the age for relaxation and longevity, but academician Lu Bingheng’s 72 years old is not the case. When we met him, he had just returned to Xi’an from a long trip, and when he landed, there were many things waiting for him to do. Lu Bingheng, academician of the Chinese Academy of Engineering, professor of Xi’an Jiaotong University, and doctoral supervisor: “There are a lot of things. Projects, reviews, mid-term inspections, on-site inspections. There are a lot of these things, there are many things on business trips, and sometimes they may travel a week. 4 After getting off the plane, Professor Lu Bingheng hurried to the Eurasian Economic Forum in Xi’an to give a report on 3D printing at a branch venue. He will try his best to make lectures like this kind of popular 3D printing common sense and very useful for promoting 3D printing.

After the report was over, Lu Bingheng hurriedly returned home and rushed to the office in Xi’an Jiaotong University, where many people were already waiting for him. A 3D printing research institute in Shanxi came to Xi’an to learn from the experience and wanted to listen to Professor Lu Bingheng’s guidance and suggestions; during the business trip, a lot of complicated tasks accumulated in the school were also waiting for him to deal with. Last year, the National Innovation Center for Additive Manufacturing, which he led by him, was established one year ago. As more and more members joined, more and more technological innovations, more and more industrialization, and Lu Bingheng’s work intensity became more and more intense. Big. Plus many projects all over the country, and he is also fast The director of the National Engineering Research Center of Rapid Manufacturing and the convener of the State Council’s Mechanical Discipline Review Group have many positions, and it is hard to imagine how busy the work is. Luo Weihong, a teacher at the School of Mechanical Manufacturing Engineering of Xi’an Jiaotong University: “It is possible that (someone) is waiting outside, and the people in front have not finished yet. In this case, sometimes it may end from 8:30 in the morning to 6 or 7 in the evening. “Xi’an Jiaotong University, School of Mechanical Manufacturing Engineering, Professor Zhang Lijuan: “He is indeed a workaholic. In the summer, he went to France on a business trip. He was originally back to Xi’an.

When he arrived at the (Xi’an) airport, he received a call from Beijing and returned to Beijing directly at the airport. Luggage Let the family go to the airport to take the luggage they brought home from France. When they arrive in Beijing, they will go to Shanghai on the day of the meeting. After Shanghai, they will go to Tianjin. After Tianjin, they will return to Xi’an, and there is a city every day.” People who have worked with him, I often forget that he is actually an old man. And it is such an old man who is spinning every day. More than 20 years ago, he started the research and achievement transformation in the field of 3D printing in China. After graduating from University in 1967, Lu Bingheng was assigned to work as a worker in a measuring instrument factory in Henan. It lasted for eleven years. The calluses on his hands during those years have only faded away in recent years, and new skin has grown. It was during the factory practice that Lu Bingheng felt that his knowledge reserves were far from enough. So in 1979, he applied for a postgraduate major in mechanical manufacturing at Xi’an Jiaotong University and stayed in school after graduation. In the early 1990s, Lu Bingheng, who was already a professor at Xi’an Jiaotong University, went to the United States for a visit, where he saw the most advanced 3D printing technology in the world at that time. Lu Bingheng, academician of the Chinese Academy of Engineering, professor of Xi’an Jiaotong University, and doctoral tutor: “I was very curious when I saw them (we) doing it with a machine, which was not our traditional manufacturing technology and did not require a mold to do it. “At that time, this field in China was still blank. Lu Bingheng judged that 3D printing will play an important role in updating and boosting the manufacturing industry in the future.

After returning to China, he started independent research and development of 3D printing technology with four doctoral students. Lu Bingheng, academician of the Chinese Academy of Engineering, professor of Xi’an Jiaotong University, and doctoral tutor: “It was very difficult at the beginning. At that time, it was mainly because of lack of funds and no money. Because the cost of developing this equipment was more than 1 million, sometimes you have to take some detours. It’s far from enough. At that time, I practiced to make a principle prototype, using domestic lasers and domestic materials. By the end of 1995, the prototype prototype came out. About the beginning of 1996, the Ministry of Science and Technology came to investigate my project. What’s going on, they were very serious at first. I took them to our laboratory to see our prototype and made the parts. They I was happy right away. “Research results have come out, and the technology is improving day by day, but how can it be used in practice? Lu Bingheng has begun to try to transform scientific research results in a timely manner, and his persistence and achievements have also attracted a large number of foreign talents to join, through enterprise operation and The comprehensive integration of production, teaching and research, the rudimentary small laboratory at the time has now become the National Engineering Research Center for Rapid Manufacturing. Lian Qin, associate professor of Xi’an Jiaotong University and School of Mechanical Manufacturing Engineering: “Our biological laboratory in the past only had a cell culture room, and that cell experiment room It’s very small, only a few square meters. Now everyone can see the entire culture room is 500 square meters, and this laboratory has divided different experiment rooms, including 3D printing room, cell culture room, you can do some experiments that could not be done in the past. . “Here, the biological laboratory has completed more than 100 3D printing transplants; 16 models of laser rapid prototyping equipment, rapid mold equipment and three-dimensional inspection equipment produced and sold by the center are used in medical, aerospace, automotive, military, shipbuilding and other industries.

Various industries. Through enterprise operation, the research center has established more than 20 innovation platforms across the country and provided rapid manufacturing services for more than 2,000 companies, which has greatly promoted the development of the entire 3D printing industry. And these are also inseparable from Lu Bingheng Academician’s hard work and dedication for more than 20 years. Lu Bingheng, academician of the Chinese Academy of Engineering, professor of Xi’an Jiaotong University, and doctoral supervisor: “One is that I have studied for so many years from elementary school, middle school, university, graduate student, and doctorate. Education and knowledge must always be given back to the society, so I think we should do as much work as possible. Secondly, we see that many aspects of our country are really in need, especially in terms of science and technology. We are actually different from advanced countries. There is little gap, but our country’s needs are very urgent. It’s a sense of mission. “At the end of the interview, it was almost dark, and the people who crowded the office just now had already dispersed. He was very worried about his granddaughter because he was on a business trip for many days. The daughter-in-law brought the child over. After playing with the granddaughter for a while, Lu Bingheng went back. Throwing into the paper at hand, his work of this day is far from over.
