China's first high-throughput integrated biological 3D printer was successfully developed
The team of scientists from Hangzhou, Beijing, Shanghai, and Guangzhou issued the first high-throughput integrated biological 3D printer in Hangzhou on the 23rd. The national key R&D project expert group appraised that this bio-printer closely matching the needs of clinical conversion and application represents the top level of China's biological 3D printing equipment, and it also means that the research level in China's related fields has been achieved from the international advanced level. And run "to "leader" across.
According to reports, the scientific research results are the results of the first year of the thirteenth five-year national key R&D program “Functional Materials for Live Devices and High-throughput Integrated 3D Printing Technology Development”.
Professor Xu Ming'en, the chief scientist of the project and the lead unit chairman of Hangzhou Jinuofei Biotechnology Co., Ltd., said that the "High-throughput integrated biological 3D printer" incorporates more than 50 technological innovations and breakthroughs, and its print heads can be compatible with a variety of printing Principles and multi-channel cooperation, so as to achieve stable mass production of medical products.
It is understood that the key technology innovation of this biological 3D printer is "discrete manufacturing micro tomography technology." Regardless of whether the basic principle is proposed or the technology is implemented, this technology is independently completed by Chinese scientists and engineers.
According to Wang Ling, an inventor of MCT technology and an associate professor at Hangzhou Dianzi University, existing imaging techniques such as CT and laser confocal are constrained by factors such as object volume, signal penetration depth, and radiation damage. MCT technology is based on micro-chromatography technology for additive imaging at the same time of additive manufacturing. In theory, the imaging depth is not limited, high resolution, non-contact, and no cell damage, and online real-time feedback control of printing parameters can be achieved for 3D. Print product lossless quality control.
The national key R&D project expert group evaluated that the successful development of the first-generation high-throughput integrated biological 3D printer not only promoted the clinical transformation process of 3D-printed medical devices and artificial tissue organs, but also provided a new solution for the screening of new drugs. The plan will promote the creation and development of new drugs in China.
The national key R&D program was formed from the integration of the original national key basic research development plan and the national high-tech research and development plan. In 2016, the national key R&D program launched the first key special project for living cells in 3D printing.
