(3Ders.org) — South Korea is using 3D printing for repairing its F-15K fighter jets, which are made by American manufacturer Boeing McDonnell Douglas. The Korean Aero Technology Research Institute called upon GE and the German 3D printer manufacturer InssTek to help create the parts with the direct metal printing Grand Teton 3D printer, its flagship 3D printer.
Due to the printer’s large build volume of 2000 x 1000 x 1000 mm, the parts were able to be printed as a single solid rather than from assembled, smaller parts. The repair was focused on the outer ring of the existing titanium alloy Ti6Al4V turbine casing. Not only would the repair help save the country over six figures annually, it would also shave off valuable repair time that otherwise would have taken several months rather than several days.Tags: Boeing, Direct Metal Printing, Grand Teton 3D Printer, InssTek, Korean Aero Technology Research Institute
