Boeing uses fuel nozzles created through additive manufacturing. In May 2017, Malindo Air received one of Boeing’s first 737 MAX 8 planes built with this new nozzle. Not only does using this lightweight, AM created nozzle simplify the assembly process for Boeing, it reduces the amount of in-flight fuel required by 15%. A boost for the airline that translates into significant environmental benefits.
Airbus is – and has been – using this technology as well. In April 2016, they announced “… some 2,700 plastic parts have been produced by additive manufacturing for the A350 XWB programme… “. Their team of experts working together to improve their planes and ensure everything is approved by the authorities.
