What companies are there in China about 3D printing?

The 3D printing industry chain mainly involves some important links such as 3D printing technology research, 3D printer production and sales (industrial and desktop level), 3D modeling, 3D printing materials production and sales, 3D printing services and so on. Introduce the situation of domestic enterprises: 3D printing technology research and industrial equipment manufacturing. Domestic research on 3D printing technology started earlier. Since 1990s, the core technology has been in the leading position, and its leading scientific research institutions are mainly some universities and their corresponding enterprises. The 3D printing equipment produced by these units are generally industrial equipment. Leading scientific research institutions mainly include Tsinghua University, Huazhong University of Science and Technology, Xi Jiaotong University and Beihang University. Enterprises relying on these institutions include Beijing Yin Hua Laser Rapid Prototyping Technology Co., Ltd., Wuhan Binhu Electromechanical Industry Co., Ltd., Shaanxi Hengtong Intelligent Machine Co., Ltd., and AVIC Laser Forming Manufacturing Co., Ltd. ... Among them, Beijing Yin Hua, Wuhan Binhu and Shaanxi Hengtong have developed industrial-grade rapid prototyping machines on the basis of independent research and development of 3D printing technology, with the business model of providing mold and original parts manufacturing services and assisting users in product development and design services. Yin Hua also develops and sells special printing consumables; AVIC laser mainly studies the application technology of laser rapid forming and installation of large-scale integral titanium alloy main bearing structure parts of aircraft, and realizes the application of laser forming titanium alloy parts in the development of civil passenger aircraft for the first time in the world. The main scientific research institutions that have carried out research on 3D printing technology but have not yet commercialized are Nanjing University of Aeronautics and Astronautics, South China University of Technology and north university of china. These universities have studied a certain rapid prototyping technology and made a rapid prototyping system. In addition, the Institute of Intelligent Manufacturing Technology of Chongqing Institute of Green Intelligent Technology of Chinese Academy of Sciences established the 3D printing technology research center in May 20 13, which will build a public technology platform for 3D printing, including five platforms: 3D printing application technology platform, material research and large-scale preparation technology platform, process research and equipment development technology platform, structure and performance evaluation platform, design and service platform. In addition, Beijing Longyuan Automatic Forming System Co., Ltd. develops and produces AFS laser rapid prototyping machines, providing samples and precision casting processing services; Nanjing Zijin Lide Electronics Co., Ltd. develops, produces and sells industrial SD300Pro series 3D printers, claiming to have an annual output of 5,000 desktop 3D printers, and develops and sells consumables.
