洛克希德·马丁在军用卫星中使用3D打印部件

“定期但不经常”通过?台媒:把台湾带入绝路“此举或将被台当局视为美国政府对它的支持。

  据外媒报道, 洛克希德·马丁(Lockheed Martin)此前已经为美国宇航局(NASA)的“朱诺”号木星探测器制造了3D打印部件,现在该公司在美国军用通信卫星上安装了第一个3D打印部件。美国空军在今年晚些时候发射的第六颗“先进极高频”(AEHF-6)卫星将包括一个称为 Remote Interface Unit的铝制航空电子设备外壳。这个设备采用3D打印技术设计和打造而成。

  Remote Interface Unit是激光粉末床熔融(Laser Powder Bed Fusion)技术制造。在这种技术中,放置一层细铝粉,由数字CAD文件控制的激光熔化粉末的选择性部分,其硬化以形成成品部件的横截面。随后放置第二层粉末,并重复该过程。完成后,除去多余的粉末和任何临时支撑物,并完成表面。

  洛克希德·马丁表示,3D打印系统允许公司用单个3D打印组件替换多个部件。这样就减少了设计和生产周期,而洛克希德·马丁公司能够在一个半月内设计出原型机,此前需要六个月。此外,生产时间从12小时变为3小时。

  完成的 Remote Interface Unit将安装在AEHF-6卫星上。AEHF卫星是军事卫星通信系统的一部分,为美国、加拿大荷兰英国等国家的陆上、海上和空中力量提供强化的全球通信战术和战略应用。洛克希德·马丁称,这种AEHF卫星与1994年-2003年期间发射的所有五颗较老的Milstar卫星具有相同的功能。

  洛克希德·马丁公司打算将新的组件作为其他计划的模式,包括用于A2100卫星平台的大型3D打印油箱。

  洛克希德马丁太空系统保护通信副总裁Iris Bombelyn表示:“3D打印通过使用一个数字模型控制生产及设计提供了快速实施创新的能力。通过为客户提供经济实惠的创新解决方案,不仅缩短了时间,同时还能够使我们适应迅速变化的军事太空环境。”
