Abstract
3D printing is an emerging technology which has been recognised not only by scientists and technology developers but also by policy-makers. However, little research has examined this promising research field using the patent bibliometric method. Thus, in this study, technology classification system for 3D printing technology is designed and the global 3D printing development characteristics are presented. Then, we use the bibliometric analysis method to rank countries, institutions, inventors and technology subfields. The results show that the global trend of 3D printing is diversified development characteristics, but technical resources distribution is not balanced. Although the 3D bioprinting is a relatively young field, it already demonstrates huge development space. With the intensification of global competition, all nations especially China should seek to enhance capability and regard effectiveness of technological innovation.
