On the morning of November 30, 2021, the Ministry of Science and Technology of the People's Republic of China organized and convened the comprehensive performance evaluation meeting of the national key R&D project report-"Micro-Nano Structure Additive Manufacturing Process and Equipment" online. The project experts listened to the report on the project from the project lead unit-Shanghai Polysun Electromechanical Technology Co., Ltd. (hereinafter referred to as Shanghai Polysun) and the project leader Professor Chen Yunfei, and strictly followed the project acceptance requirements, reviewed and inspected the entire project. Relevant materials and the actual implementation of the project, after inquiries and discussions by the experts of the expert group, agreed that the project fully meets the acceptance criteria, and agreed to pass the comprehensive performance evaluation of the project.
It is reported that the project was approved by the National High-Tech Research and Development Center of the Ministry of Science and Technology on July 25, 2018, with Shanghai Polysun as the lead unit of the project, based on the original technology of independent intellectual property rights, and led Southeast University and Huazhong Science and Technology Seven universities, including Nanjing University, Nanjing University, University of Science and Technology of China, Nanjing University of Aeronautics and Astronautics, Changchun University of Science and Technology, East China University of Science and Technology, and Suzhou Saifei Group Co., Ltd., formed a R&D team, from common technology, cutting-edge technology, key technology and equipment , Starting from four levels of application demonstration, breaking through multiple technical barriers in the micro-nano field.
According to Shanghai Presen, the national key research and development project that is the lead application is my country's first major project in the direction of micro-nano additive manufacturing.
The main difference between micro-nano 3D printing technology and "traditional" 3D printing is that the precision of micro-nano 3D printing can reach the level of micro, micro and nano (that is, one billionth of a meter). This feature enables micro-nano-scale 3D printing to manufacture micro-level devices, such as microfluidic chips, cell scaffolds, and microsensors. And the manufacturing cost is greatly reduced, and the integrated intelligent printing production of micro-nano devices is realized at a very low cost.
Social development needs the promotion of science and technology, and the research on micro-nano has always been the frontier of science and technology in the world. It can obtain completely different characteristics from the macro-scale. Traditional crafts often use mems processing techniques similar to chip manufacturing, and the cost is very high. It is expensive, and even so, it cannot be effectively realized in the face of complex structures. Plysun Micronano 3D printing technology can overcome these challenges and make the customization of complex parts easier. According to the data of Prison, the production speed of this technology is thousands of times faster than the "two-photon micro-nano 3D printing technology".
The project of "Micro-Nano Structure Additive Manufacturing Process and Equipment" led by Shanghai Polysun has promoted the good development of micro-nano printing technology. Shanghai Pulisheng stated that in the future, it will continue to deepen the micro-nano field based on its existing advantages, further explore and improve micro-nano-related processes and equipment, and contribute to the realization of the country’s "14th Five-Year Plan" goal and help promote the grandeur of a "powerful country in science and technology". Vision.
