本文介绍了选择性激光熔化（SLM）制造微波波导器件的研究进展。后者是一种基于通过激光选择性熔化金属粉末床的增材制造工艺。讨论了该技术在卫星通信（SatCom）天线馈电链开发中的应用。介绍了零件电磁性能评估的过程和实验活动。将介绍通过SLM制造的Ku/ k波段滤波器和Ku波段馈线喇叭的测量性能。结果表明，SLM技术在开发新组件和提高系统集成度方面具有重要的应用价值。
This paper presents the developments at CNR-IEIIT and IIT concerning microwave waveguide components manufactured through selective laser melting (SLM). The latter is an additive manufacturing process based on the selective melting of a metal powder bed through a laser. Application of this technology to the development of antenna-feed chains aimed at satellite communication (SatCom) is discussed. Description of the process and experimental activities for the assessment of the electromagnetic properties of parts are reported. Measured performance of Ku/K-band filters and Ku-band feed-horns manufactured through SLM will be presented. The results achieved prove that SLM can be a valuable technology both to develop novel components and to increase system integration.
