通过在航空工业中使用激光添加剂制造钛零件,中国正在在商业化3D打印技术领域成为全球领先。

这种激光添加制造技术不仅能够使钛零件的成本降为原来的5%,还能降低零件重量并增加复杂零件的强度。

据中国媒体“观察者”报道,如果美国的F-22上的钛零件使用中国的3D打印技术制造,那么多达40%的重量可以被缩减。

在政府,特别是军方经费的支持下,中国航空激光技术团队正在为国家第五代战斗机J-20和J-31制造钛零件,这可以降低成本,同时增加战斗机的推力-重量比例。


同时,西北工业大学也正在为C919客机制造5米长的钛机翼,计划于2016年投入到商业运行。

“随着航天技术的发展,零件正变得更轻便,更复杂,同时应该有更好的机械性能,”这个大学实验室的导师黄卫东对当地的报纸说。“使用传统技术很难制造这样的零件,但是3D打印技术正好满足这样的需求。”

英文原文:China commercializes 3D printing in aviation

By Liu Jiayi for View from China |February 18, 2013 -- 02:45 GMT (18:45 PST)

By using laser additive manufactured titanium parts in its aviation industry, China is looking to become a global leader in commercializing 3D printing technology.

The laser additive manufacturing technology not only lowers the cost of titanium parts to only 5 percent of the original, it also reduces the weight of the components and enhances the strength of complicated parts.

As much as 40 percent of the weight can be reduced if the forged titanium parts on an American F-22 were made using the Chinese 3D printing technology, according to a a report on Chinese Web site, Guancha Zhe.

With funding from the government, especially from the military, the Chinese aviation laser technology team is making headways in making titanium parts for the country's fifth generation of fighter jets, the J-20 and J-31, by lowering the cost and raising the jets' thrust-weight ratio.

The Northwestern Polytechnical University of China is also making five meter-long titanium wing beams for the C919 passenger plane, which is scheduled to be put into commercial operation in 2016.

"As the aviation technology develops, the components are also getting lighter, more complicated, and also need to have better mechanical properties," said Huang Weidong, director of the university's laboratory, to a local newspaper. "It is very hard to use traditional technologies to make such parts, but 3D printing could just meet such demands."
