去年年底从Euromold发出的氛围是为更大的应用程序扩展3D打印机。雷电竞app下载
Well, one of the biggest 3DP applications I’ve ever seen in metal came to light last week and it is, unsurprisingly, an aerospace part that has been developed at The State Key Laboratory of Solidification Processing, part of the North Western Polytechnical University (NPU) in China. This institute has been conducting extensive research with Laser Additive Manufacturing (LAM) systems since 1995 with a focus on garnering superior mechanical properties of metal parts produced in this way through careful control of the material microstructures. The aim being, to produce production-grade parts, which are capable of meeting the strict aerospace manufacturing regulationsand提供了比传统制造技术的关键优势 - 重量更轻，强度改善是两种主要优势。
NPU实验室总监Huang Weidong表示：“现代航空航天行业有严格的要求，因此必须开发复杂的添加剂制造过程，以确保产品能够达到传统制造方法确定的稳健性能水平。”雷电竞充值
The part in question, which can be seen in the accompanying images, is a 3D printed, titanium central wing spar — it is 3 metres long and the mechanical properties of this part reportedly meet standards achieved by forging. As a result the wing spar is due to be assembled on a Comac C919 passenger-plane in 2014, and subsequently enter commercial service in 2016. The part was produced on LAM systems developed in house at NPU.
This is big news (pun intended) and takes AM to a level that, while predicted, has really only been hypothesized to date on this scale!
