摘要
3D打印技术在全球范围内日益受到重视,各国不断加大研发投入,拓展其在航天航空、军事、汽车制造、家用电器等方面的应用,使3D打印技术逐步成为未来制造业发展的关键性技术之一。该文以德温特创新索引Derwent Innovation Index数据库为数据源,利用Thomson Innovation、Thomson Data Analyzer、Excel等工具完成检索式构建及数据采集、清洗、分析等工作,对全球3D打印技术相关专利进行定量分析,揭示该领域专利技术的发展态势。
The development of 3D actively in technology research and printing develop has attracted worldwide concern, most of cotmtries have funded ment. 3D printing has been widely used in many fields, such as aerospace, military, automotive manufacturing, household appliances. It became one of the most important technology of manufacturing industry gradually. Based on the patents data from the Derwent Innovation Index, the state of the arts of 3D printing has been processed by using the statistical tools the TDA and Excel. By analyzing the population distributions of the patents as a of the Thomson Innovation function of a parameter o International Patent Classification （IPC） such as time, patentee, and technical field, the technology development trend in 3D printing has been identified. The results provide a reference for the industry development scheme in this field.
