:作为中航工业沈阳飞机设计研究所副总设计师、飞机结构3D打印应用技术的领军人物,请您介绍一下我国3D打印技术的发展。王向明:3D打印是增材制造技术的俗称,该技术具有结构设计、材料制备、构件成形一体化,无需模具及传统大型工业装备,材料利用率高,成本低,数字化,快速响应等特点。国内3D打印技术研究始于20世纪90年代初,主要集中在高校和研究机构,包括西安交通大学、华中 : As the AVIC Shenyang Aircraft Design Institute deputy chief designer, aircraft structure 3D printing technology leader, please tell us about the development of China’s 3D printing technology. Wang Xiangming: 3D printing is commonly known as additive manufacturing technology. The technology has the features of structural design, material preparation, component forming and integration, no mold and traditional large-scale industrial equipment, high material utilization rate, low cost, digitalization and quick response. Domestic 3D printing technology research began in the early 1990s, mainly in universities and research institutions, including Xi’an Jiaotong University, Central China
