金属3D打印技术及其专利布局分析

The Patent Portfolio Research of Metal 3D Printing

金属3D打印技术是近年来最前沿、最有潜力的先进制造技术之一。本文通过分析金属3D打印技术发展构建了专利检索式,分析了全球的专利布局态势。分析认为,我国虽拥有全球第一的3D打印技术专利申请量,但核心专利相对较少,未来应着力突破关键技术,提高核心专利质量,促进我国金属3D打印的技术创新。

In recent years, 3D metal printing technology is the most promising advanced manufacturing technology. This paper builds a patent search model by analyzing the development of 3D metal printing technology, and analyzes the global patent situation. According to the analysis, although China＇s 3D printing technology patent applications ranks first in the world, there are only a few core patents relevant. Therefore, in the future, we should focus on the breakthrough of key technologies, improve the quality of core patents, and promote the technological innovation of 3D metal printing in China.
