【本刊讯】GE公司航空事业部近日计划扩充3D打印制造规模,并将借助3D打印用于制造喷气发动机的燃料喷嘴。今年下半年开始,3D打印机将陆续就位,Auburn工厂将与明年正式开始3D打印产品级零部件。预计到明年年底,该工厂将配备10台3D打印机,占其生产能力的三分之一,计划最终3D打印机数量将超过50台,而Auburn也将专门制造LEAP喷气发动机的燃料喷嘴,成为首家大规模采用增材制造技术的工厂。与传统车床或金属切割机的制造方式不同,3D打印主要是由激光或电子束,根据CAD文件逐层熔融细 [Print] GE Aviation recently plans to expand the scale of 3D printing manufacturing, and will use 3D printing for the manufacture of jet fuel nozzles. The second half of this year, 3D printers will be put in place, Auburn factory will officially begin next year, 3D printing product-level components. It is estimated that by the end of next year, the plant will be equipped with 10 3D printers, accounting for one-third of its production capacity and plans to eventually have more than 50 3D printers and Auburn will also be the first to manufacture LEAP jet fuel nozzles Large-scale use of additive manufacturing technology factory. Unlike traditional lathes or metal cutting machines, 3D printing is mainly done by laser or electron beam, depending on the CAD file
