Abstract: In the patent database of State Intellectual Property Office of China, the related patents for 3D printing of precious metals in jewelry are searched and screened, and then the patent information is counted and analyzed. This paper analyzes the status quo of domestic precious metal used in jewelry 3D printing technology patents from the perspective of patent information analysis, including the validity of patents, the types of disclosure, patent applicant, IPC classification, etc. And IPC Technology Association, patent applicant's technology field, patent geographical distribution are analyzed emphatically. Based on the analysis of the patent information of precious metal 3D printing and combined with the actual situation of the jewelry industry, it is found that there are some problems in the technology and industry of precious metal 3D printing in China, such as the lack of intrinsic motivation of metal 3D printing enterprises, the lack of relevant technical researchers, the low scale of the jewelry industry, and the imperfect policy system of promoting precious metal 3D printing of jewelry. In order to promote the healthy and rapid development of China's precious metal 3D printing industry, the development strategies and policy suggestions are put forward, such as increasing investment in the construction of precious metal 3D printing industry, building precious metal 3D printing industrial park, establishing a practical training system for professional education personnel of jewelry 3D printing, integrating jewelry parks and extending the industrial chain for relevant enterprises, increasing support for related enterprises and so on.
