Air New Zealand to use 3D printing to create aircraft cocktail trays

WELLINGTON (Reuters) - Air New Zealand said it has created cocktail trays for its business class section using 3D printers and is looking at employing the technology further as it seeks to better control replacement stock and cut manufacturing costs. The airline aims to install the trays in the coming weeks once it receives regulatory approval. "A big advantage of 3D printing is that it allows us to make cost-effective lightweight parts ourselves, and to do so quickly without compromising on safety," Air New Zealand Chief Operations Officer Bruce Parton said in a statement. Additive manufacturing, or 3D printing, is used to build objects by adding layer-upon-layer of material, such as plastic or metal. The technology poses a threat to traditional manufacturers who may increasingly see clients build their own parts or products. Parton said Air New Zealand was looking to use 3D printing more as sourcing aircraft parts from manufacturers was costly and caused storage problems. "We often only require a small number of units which can be really expensive to produce using traditional manufacturing methods and can involve frustrating delays while a replacement part is delivered," he said. Aircraft and aerospace companies are increasingly looking to addititive manufactuing to produce engine parts. Aerojet won a U.S. air force contract last month to work on standards to create 3D printed rocket engines. Rocket Lab, which has contracted with NASA and private companies to provide low-cost rocket launches out of New Zealand this year, has designed the world's first 3D printed rocket engine.
