A trim-and-drill tool that will be tested during construction of the Boeing Co.’s next-generation 777X jet has already produced something notable: recognition from Guinness World Records as the world’s largest solid 3-D-printed object.
The trim tool, developed at the Department of Energy’s Oak Ridge National Laboratory in Tennessee, was made in only 30 hours using carbon fiber and ABS thermoplastic composite materials. It’s 17.5 feet long, 5.5 feet wide and 1.5 feet tall, and weighs about 1,650 pounds.
After Oak Ridge completes verification testing, the tool will get its tryout at a Boeing production facility in St. Louis, Mo. It’ll be used to secure the jet’s composite wing for drilling and machining before assembly.
