One for the record books

The 777X hasn’t even started production, but it’s already helping set new records. A 3D printed wing trim tool for the airplane, developed by Boeing and researchers at the Oak Ridge National Lab in Tennessee, now holds the GUINNESS WORLD RECORDS™ title of the largest solid 3D printed item.


Official measurement of the 3D printed trim tool co-developed by Oak Ridge National Lab and Boeing.

The lower cost trim tool was printed in only 30 hours using carbon fiber and ABS thermoplastic composite materials. The tool will be used to secure the 777X’s composite wing skin for drilling and machining before assembly.


At 17.5 feet long, 5.5 feet wide and 1.5 feet tall, the 3D printed structure is comparable in length to a large sport utility vehicle and weighs about 1,650 pounds.


Coming soon— the 777X itself.

Additively manufactured tools, which save energy, time, labor and production cost, are part of Boeing’s strategy to apply 3D printing technology in key production areas.

Thanks to the folks at Oak Ridge for helping us come up with one for the record books.

Getting a Guinness Book of World Record recognition is not a bad way to start the production next generation of 777 aircraft. Congrats to the 777 team and Boeing on receiving that honor.
