Additive manufacturing technology(3D printing) can not only greatly save raw materials, but also enable designers to quickly realize and verify the design scheme. 3D printing can solve the problems of traditional complex technological process, long cycle and low utilization rate of raw materials. It is regarded as an important opportunity to promote a new round of industrial revolution. Patent documents are one of the largest sources of information in the world. 90% ～ 95% of the world's invention and creation achievements can be found in patent documents every year.In this paper, the patent document of 3D printing related to aeronautic field was retrieved. The patent application and the applicant, the global geographical patent layout, an application for a patent for the technical direction and technology category distribution, multidimensional patent information are analyzed. Development roadmap of additive manufacturing technology is clarified, and the developing trend of technology is forecasted. Suggestions are put forward, such as strengthening the construction of talent team, accelerating the investment in technological research and development, strengthening the protection of intellectual property rights of innovation achievements, timely building the alliance of additive manufacturing industry, tracking the patent application trend of major competitors, etc.Through this paper,the potential risk of infringement of intellectual property can be avoided, and the reference for the development of manufacturing technology in aviation field is provided.
