The research team of Nanjing University of Technology has cooperated with Nanjing Economic and Technological Development Zone and Zhongke Yuchen Laser Technology Co., Ltd. to establish a new research and development institution "Additive Manufacturing Powder Material Research Institute", the first titanium alloy powder with China's independent intellectual property rights. The production equipment is expected to be installed and commissioned at the end of September. After large-scale production, the price of titanium powder is expected to drop by half.

Professor Chang Hui, Executive Dean of the Institute and Deputy Dean of the School of Materials Science and Engineering of Nanjing University of Technology, said that titanium has the characteristics of light texture and good flexibility. It is an important structural metal in the current manufacturing field and naturally has become an important raw material for 3D printing. . Chang Hui said that titanium alloy is an important structural material in the aerospace field, but currently domestic titanium powder has poor stability and consistency, which causes large fluctuations in the performance of printed parts, affecting the batch application of 3D printed titanium alloy components in important projects. . At present, a large part of the titanium alloy powder used in domestic aerospace additive manufacturing technology needs to be imported from abroad. More than 80% of the equipment for producing and preparing titanium alloy powder is also purchased from abroad.
At present, they have completed a series of preliminary verification and other tasks. At the end of September, the first domestically-made titanium powder manufacturing equipment completely designed and developed by China will be in place. "After large-scale production, the price of titanium powder is expected to drop by about half compared to now." Chang Hui said that after the cost of titanium powder is reduced, it can be used in daily life. "For example, a vascular stent, a titanium stent made of titanium alloy has good affinity and corrosion resistance, which is more ideal than a steel stent. After the cost is reduced, more people can afford it."
