[Abstract] in May 23rd, the first Sino German manufacturing forum hosted by Nanjing University of Aeronautics & Astronautics and Darmstadt Industrial University, Germany, was held in Nanjing. Reporters learned from the meeting, the rapid development of 3D printing technology, not only can make 3D aircraft, but also print human organs, experts predict that within 5-10 years, the technology will be applied to the laboratory.
The intersection point in May 23rd by the Nanjing University of Aeronautics & Astronautics and the German Darmstadt Industrial University hosted the first session of the Sino German manufacturing forum held in Nanjing. Reporters learned from the meeting, the rapid development of 3D printing technology, not only can make 3D aircraft, but also print human organs, experts predict that within 5-10 years, the technology will be applied to the laboratory.
In the field of aviation, 3D printing is to enhance the manufacturing level of the aircraft, made large aircraft C919 first successful application of 3D printing titanium alloy parts, mechanical performance was significantly higher than that of the original cast, and effective parts to shorten the delivery cycle, effectively ensure product performance requirements. Jiang Liping, chief engineer of the assembly manufacturing center of China commercial fly Corporation, said: "the future of composite 3D printing will realize agile production, not only reducing material costs, but also shortening the manufacturing cycle."." Reporters learned that, through the upgraded version of 3D printing technology, the current aircraft landing gear, engines, including wings have achieved a successful print, so that aircraft manufacturing has become increasingly simple.
The upgraded version of 3D printing technology can not only print airplanes, but also print human organs. "3D printing technology upgrade to the external environment, based on the original 3D print on the stimulus, with time to achieve self 'growth', we called 4D printing, both at home and abroad began to increase the laboratory materials research and development of intelligent materials manufacturing." Chinese Academy of Engineering Lu Bingheng told reporters, "in layman's terms, print is flat, but as long as a little magnetic field, things can stand open, shape and function change.". Foreign countries have started related research, found that 4D printing of nerve cells in response to the outside world, such as artificial bone, bone cells can grow their own, and even artificial liver, artificial retina, can be carried out through the chemical reaction technology."
"At present, artificial print skeletons have been achieved and achieved success in animals." Academician Lu Bingheng further said, "first with" bone marrow mud print a "material skeleton, hung on the cultured sheep bone tissue, cell growth factors, tissue hanging scaffold, bone cells begin to grow, the growth will have biochemical role into bone cells themselves, printing material the degradation was dropped, become bone cells composition. Half a year later, the long bone of mutton. The technology is expected to move from lab to lab within 5-10 years."
