全金属无源波导元件是用于电信、导航、成像、射电天文学和宇宙学的几种RF系统的关键构件。在增材制造（AM）技术中精确制造这些器件可以为微波功能的高集成度开辟道路，同时显着降低成本和质量。在本文中，在介绍了最常见的AM技术，特别是选择性激光熔化（SLM）和立体光刻设备（SLA）的过程中，正在进行的研究活动的结果进行了讨论。测量性能报告AM原型Ku/K/Ka波段矩形和圆形波导线，微波滤波器和光滑的壁喇叭。
All metal passive waveguide components are key building-blocks of several RF systems used for telecommunications, navigation, imaging, radio-astronomy, and cosmology. The accurate manufacture of these devices in Additive Manufacturing (AM) technologies can open the way to a high integration level of microwave functionalities with a significant cost and mass reduction. In the paper, after an introduction on the most common AM technologies with particular detail on selective laser melting (SLM) and stereo-lithography apparatus (SLA) processes, the results on the on-going research activity are discussed. Measured performances are reported for AM prototypes of Ku/K/Ka-band rectangular and circular waveguide lines, microwave filters and a smooth wall horn.
