Stratasys的3D印刷服务局，RedEye，，，，has proven the feasibility of creating large industrial parts with 3D printing technology by manufacturing one of the world’s largest 3D printed parts forLockheed Martin’s Space Systems Company。15英尺长的燃油箱原型是洛克希德（Lockheed）的卫星形式，合身和功能验证测试的两个制造的产品之一，帮助他们以几乎一半的时间和成本与传统制造业一样将产品推向市场。
使用Redeye的融合沉积建模（FDM）在Fortus 900MC上的过程中，两个储罐中的较大较大的较大的材料是从10个不同的零件组装而成的，而使用聚碳酸酯（PC），较小的零件是由6件制成的。完全，打印过程花费了将近两个星期，平均每节约150小时。由于所制作的零件的大小，因此使用定制固定装置来支撑各个细分市场，因为它们被粘合在一起。制造后，将零件加工成符合公司规格，最终组装坦克总计240小时。您可以观看以下加工过程的简短片段：
RedEye’s strategic account manager for aerospace and defense, Joel Smith, describes the milestones reached by the project, “This project is unique in two ways – it marks the first aerospace fuel tank simulation produced through additive manufacturing and is one of the largest 3D printed parts ever built. Our ability to accommodate such a large configuration and adapt to design challenges on the fly, demonstrates that there really is no limit to the problem-solving potential when you manufacture with 3D printing.透明
在这种情况下，使用增材雷电竞充值制造业使国防承包商能够在一半的时间内通过加工来创建其零件，从而在竞争性合同投标过程中具有优势，而洛克希德·马丁太空系统公司高级制造工程师安德鲁·布什尔（Andrew Bushell）表示，他说。，，，，“With RedEye’s machine capacity and engineering support, we were able to successfully build these tank simulators in a fraction of the time and at a fraction of the cost.”
The tanks successfully passed a number of quality assurance and accuracy measurements and underwent Lockheed’s form, fit and function testing. The next phase of the project will see the company print its second iteration of tanks, ultimately aiding in the optimized design of their satellites. More importantly, the prototypes, RedEye’s largest parts to date, show off the ability of 3D printing to be used for big objects, despite the limitations of a 3D printer’s build volume.
