Boeing’s technologically advanced and fuel efficient 787 Dreamliner may soon have 3D printed parts. That’s according to Norsk Titanium, an Oslo-Norway based company that manufacturers titanium products for airplanes.

“We are proud to take this historical step with a great aerospace innovator like Boeing,” said Norsk Titanium President & Chief Executive Officer Warren M. Boley, Jr. in a press release. “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.”

You can see the new 3D printed parts at the Paris Air Show starting on June 19 – they will be on display.

“From the outset, the 787 has been the hallmark of innovation and efficiency,” said John Byrne, vice president, Airplane Materials and Structures, Supplier Management, Boeing Commercial Airplanes in a press release. “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.”

The 3D printed parts are expected to dramatically cut production costs for the Boeing 787 Dreamliner, which has just recently become profitable for Boeing.

The Boeing 787 already stands out from its peers thanks to its fuel efficient carbon fiber fuselage. The fuselage is lighter than an aluminum one and is also the reason why the Boeing 787’s windows are 30% larger than other planes.
