“…An example of an OMT realization of an AMoriented geometry is reported in Ref. [41], where the RF measured performances well match the simulated one. Isolation over 50 dB and return loss better than 20 dB have been achieved in the operative frequency range.…”

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.

“…At first, AM technologies have been investigated for the development of stand-alone components relevant to satellite communication payloads, including straight and meander waveguides [47], [48], filters [49], [50], [51], [52], [53], [54], ortho-mode transducers/polarizers [55], [56], [57], [58], [59], and radiating elements, such as helix/quad-ridge antennas [23], [60], [61], and feed horns [57], [62]. Investigations on the multipactor performance of AM components have also been carried out [63].…”

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.

“…Other research groups concentrated on metamaterial filters for the K-band [98], waveguide antennas for the Ku band [99,100] or other bands [101,102]. Generally, here the mechanical and thermal requirements are less rigorous in comparison with the aforementioned applications; thus, most studies are based on state-of-the-art metal additive manufacturing, taking into account design for the respective technique and possibly a postprocessing step to avoid too high roughness.…”

The emerging technology of 3D printing can not only be used for rapid prototyping, but will also play an important role in space exploration. Additive manufactured parts can be used in diverse space applications, such as magnetic shields, heat pipes, thrusters, etc. Three-dimensional printed parts offer reduced mass, high possible complexity, and fast printability of custom-made objects. On the other hand, materials which are not excessively damaged by the harsh conditions in space and are also printable by available technologies are not abundantly available. This review gives an overview of recent metal additive manufacturing technologies and their possible applications in space, with a focus on satellites and rockets, highlighting already applied technologies and materials and gives an outlook on possible future applications and challenges.
