2012年,中国商飞公司与西北工业大学联合攻关,成功利用3D打印技术制造C919飞机的大型钛合金结构件——中央翼缘条。这一重大技术突破,将助力C919大型客机早日翱翔蓝天。3D打印技术又称三维打印技术、增材制造技术等,是指通过可以“打印”出真实物体的3D打印机,采用分层加工、迭加成形的方式逐层增加材料 In 2012, China Commercial Aircraft Corporation and Northwestern Polytechnical University joint research, the successful use of 3D printing technology to manufacture large titanium alloy C919 aircraft structure - the central flange. This major technological breakthrough will help C919 large passenger aircraft soar in the blue sky. 3D printing technology, also known as three-dimensional printing technology, additive manufacturing technology, refers to the Through the “print ” out of the real object of the 3D printer, using layered processing, superposition of ways to increase the material layer by layer
