Norsk Titanium 3D prints world’s first approved, structural, titanium components for commercial flight

挪威航空航天添加剂制造专家雷电竞充值Norsk Titanium as，已发布跨国飞机公司零件顺序的详细信息波音(NYSE: BA). According to Norsk, the ordered components will make the Boeing 787 Dreamliner the“第一款商业飞机在结构应用中使用经过认证的添加剂制造的钛零件飞行。”

A “new and creative way” of producing metal parts

The titanium Dreamliner parts were 3D printed using Norsk’s proprietary Rapid Plasma Deposition™ process, where a wire feedstock is melted in a build area containing argon gas. Building layer by layer, the Rapid Plasma Deposition™ method produces a near-net-shape which is up to 80% complete before post-processing is undertaken.

波音商业飞机的飞机材料和结构副总裁约翰·伯恩（John Byrne）评论说：

From the outset, the 787 has been the hallmark of innovation and efficiency. We are always looking at the latest technologies to drive cost reduction, performance and value to our customers and Norsk Titanium’s RPD™ capability fits the bill in a new and creative way.

Honored with FAA approval

Testing for FAA approval of Norsk Titanium’s parts was completed in February 2017, assuring their “airworthiness”.根据FAA文件，这可以分解为两个条件：

“飞机必须符合其类型的设计。”即零件与以前在类型证书（TC）中确定的参数一致，该参数涵盖了飞机的所有不同部分。
“飞机必须处于安全操作的条件下。”考虑到材料的腐蚀，气压和对元素应力的反应引起的裂纹。

Norsk Titanium总裁兼首席执行官Warren M. Boley，Jr。说，

We are proud to take this historical step with a great aerospace innovator like Boeing. The Norsk Titanium team will continue to expand the portfolio of components supplied to Boeing meeting stringent certification requirements. It is an honor to earn FAA approval for these structural parts.

An additive manufacturing strategy

在国防智商Additive Manufacturing for Aerospace, Defense and Space conference我们的主编获得了insight into Boeing’s additive manufacturing strategyfrom Leo Christodoulou, Director of Structures and Materials, Enterprise Operations and Technology. At the conference Christodoulou, commented that“AM will dominate tooling”,然后“I’m not going to stick around for someone’s dream to come true, we just have to do it”.

In metal additive for aerospace, there have also be significant effort into production of high-stress components, such asSpaceX’s 3D printed SuperDraco thrusters，和Aerojet Rocketdyne的铜推室.

正如我们最近报道的那样，wire deposition methods of additive manufacturing are also the focus of new companies looking to move into this sector.
