以空中客车公司生产的机舱门铰链为例，用三维喷射技术取代原有注射成型工艺可使铰链的重量减少一半，不但节省了大量生产材料，在这些铰链全球飞行的生命周期中也随之减少了许多燃料消耗。
For example, when Airbus moved from injection molding to 3D printing to produce the metal hinges for its airplanes’ doors, it reduced their weight by half, yielding phenomenal savings in material and associated fuel consumption over a lifetime of flying those hinges around the world.
