Which companies in China support 3D printing of "metal materials"?

Two years ago, when 3D printing was just beginning to be popularized, there were few domestic enterprises doing metal 3D printing, and most of them were universities or research institutes. Up to this year, the bosses in the laser industry and CNC lathe industry have basically blossomed everywhere, either independently researching and developing or cooperating with the support of the government. But the dominant ones are the original ones. The application direction is in addition to some military fields. In the civil field, everyone is more optimistic about the application of the medical industry. Mainly include: Xi Anbo Park Jung Su Laser Forming Technology Co., Ltd. and the team of Professor Huang Weidong from Northwestern Polytechnical University. The military and aerospace fields have done well, and now the market is relatively mature. AVIC Tiandi Laser Technology Co., Ltd., Southern Additive Technology Co., Ltd. ... Professor Wang Huaming from Beihang University cooperated with two listed companies. You can check it yourself. But it seems that no mature equipment has been introduced so far. Wuhan Binhu Electromechanical Technology Industry Co., Ltd., led by Professor Shi Yusheng from Huazhong University of Science and Technology, started 3D printing earlier in China, and it was also a metal 3D printing device that was introduced to the market earlier. But now it seems that the reorganization of Huake's school-run enterprises will be acquired by the newly formed Huake 3D. Guangdong Xindaya 3D Technology Co., Ltd. and the team of Professor Yang Yongqiang from South China University of Technology have made a good medical market in the field of metal 3D printing. The above are the technical representatives of domestic metal 3D printing and the representatives of self-developed equipment. As for the metal 3D printing claimed by many other companies, many of them have bought some EOS, and machines like Lei Nishao are doing some processing services. To tell the truth, these machines are not cheap either, a few million, and the price is twice that of domestic equipment.
