“…For this technology, further studies have been focused on the integration of different functionalities in a single mechanical part. To this end, the AM free-form capability has been exploited as much as possible to achieve significant benefits in terms of mass, envelope, and assembling complexity [70], [71], [72], [73], [74], [75], [76].…”

3D-printing is leading to a major transformation in many industrial and application sectors, ranging from medical to aerospace. In the space sector, 3D-printing has firstly been adopted for the development of structural and thermal parts, such as brackets and heat pipes. In more recent years, thanks to improvements in precision and surface roughness, 3D-printing technologies have steadily been investigated also for the development of radio frequency components and advanced payloads. Indeed, the unique features of 3D-printing, including the free-form capability and the ease for customization, make these manufacturing technologies very appealing in the development of complex radio-frequency front-ends for space applications, including New Space constellations and next generation software-defined communication satellites. They also enable a drastic simplification of mechanical designs by reducing the number of interfaces and assembling screws of large radio-frequency front-ends, thus leading to significant mass savings and higher integration. This paper briefly reports on recent advances in 3D-printing that have been carried out according to the current trends in radio-frequency front-ends for satellite communications.

The exponential growth of publications, in the last years, on the use of additive manufacturing (AM) technologies in the microwave field proves the increasing interest of research institutions and industries in these techniques. Some advantages of AM with respect to conventional machining are weight reduction, design flexibility, and integration of different functionalities (electromagnetic, thermal, and structural) in a single part. This chapter presents the most employed AM technologies for the manufacturing of RF waveguide components. First, an overview of the AM processes is discussed with particular care on material properties and post-processing. Then, an extensive survey on microwave-guided components fabricated by AM processes published in literature is shown.
