Abstract：We analyze the type and time series from patent,the patent holder and the respective technical areas,technology life cycle of patent,patent portfolio,patent licensing and other aspects of the legal status of 3D-printing technology based on patent map.The results show that 3D-printing technology of China has been out of the technology bud and is in a rapid growth stage.However,the quality and value of the patent should be further improved.B29C,B22F,B41J,B28B have rapid development,and B29C and B41J have great potential development,but B22F and B28B are subject to certain restrictions.China needs to further strengthen efforts to support 3D-printing technology.Technology research and development should focus on the promotion of technological innovation of 3D-printing and industrial transformation
