coondoggie quotes a report from Network World: A 17.5 foot long, 5.5 foot wide and 1.5 foot tall the 3D printed aircraft design tool has earned the title of largest solid 3D printed item by Guinness World Records. The 1,650 lb. apparatus known as a trim-and-drill tool is comparable in length to a large sport utility vehicle and will ultimately be tested for use in building the Boeing 777X passenger jet. Basically the tool will be used to secure the jet's composite wing skin for drilling and machining before assembly, according to researchers at the Department of Energy's Oak Ridge National Laboratory (ONRL) who developed the tool. "The existing, more expensive metallic tooling option we currently use comes from a supplier and typically takes three months to manufacture using conventional techniques," said Leo Christodoulou, Boeing's director of structures and materials in a statement. "Additively manufactured tools, such as the 777X wing trim tool, will save energy, time, labor and production cost and are part of our overall strategy to apply 3D printing technology in key production areas."
