摘要
现有研究缺少对金属增材制造闭环控制技术的对比分析,基于授权专利角度的针对性分析未见报道,借此分析为我国金属增材制造产业发展提供借鉴和参考。深入调研金属增材制造不同技术的最早发明专利以及目前全球增材制造领域知名企业的核心专利,进行人工去噪后针对性分析目前授权有效专利和期限届满专利。深入对比分析了金属增材制造闭环控制技术,初步归纳了其技术发展规律和路线。
Previous studies lack comparative analysis of the closed-loop control technology of metal additive manufacturing,and there is no report on the targeted analysis from the perspective of authorized patents.This paper did that job to provide reference for the development of our country's metal additive manufacturing industry.This paper investigated the earliest invention patents of different technologies in metal additive manufacturing and core patents of well-known companies in the global additive manufacturing field with focus on targeted analysis of currently authorized valid patents and expired patents.This paper compared and analyzed the closed-loop control technology of metal additive manufacturing deeply,and summarized its technological development laws and routes.
