Boeing turns to 3D-printed parts to save millions on its 787 Dreamliner

The move will reduce production costs for each Dreamliner by $2 million to $3 million.

Boeing will begin using at least four 3D-printed titanium parts to construct its 787 Dreamliner aircraft and may some day rely on as many as 1,000 parts created via  additive manufacturing.

Boeing has hired Oslo, Norway-based Norsk Titanium AS to print the parts. It marks the first time that FAA-approved, 3D-printed titanium parts will be used as structural components on a commercial aircraft, according to the company.

The parts will be used near the rear of the Dreamliner, a mid-sized, wide-body, twin-engine jet airliner. Boeing builds about 144 Dreamliners each year.

Printing 3D parts for Boeing will allow the aircraft manufacturer to eventually reduce the production costs for each 787 Dreamliner by as much as $3 million, Norsk Titanium said.

"We are providing Boeing with an initial quantity of four parts per 787 airplane and are actively working to expand this order to possibly more than 1,000 parts per airplane, which if we achieve, could save Boeing $2 million to $3 million per airplane some years from now," a Norsk Titanium spokesman said via email to Computerworld. "If we achieve our goal of selling over 1,000 parts per 787, they would be located in a wide variety of structural applications."

The use of 3D printing technology is growing at an exponential rate, Boeing said, and interest in using it "has increased dramatically during the past few years."

"3D printing offers great potential to reduce the cost and weight of aircraft structures and improve the ability of engineers to design parts purely for their eventual function in a vehicle system," a Boeing spokesperson said in an email. "3D printing enables the design and production of integral structures. This means converting an assembly and several structures into one piece."

Boeing's use of Norsk Titanium's parts is not the company's first foray into the use 3D printing technology.

Last year, Boeing said it was testing an industrial 3D printer from Stratasys that can build objects of virtually any size using materials such as carbon fiber for lighter weight and stronger parts. The printers were designed to address the requirements of aerospace, automotive and other industries by being able to build completed parts with repeatable mechanical properties.
