“…5. As can be seen in the plot, the centre frequency of the casted resonator was off by 0.2 GHz from the designed frequency, which corresponds to a change in the total height of the cavity of 0.6 mm using (1). This loss of height can be attributed to the incomplete burning of the PLA, leaving a slight layer at the bottom of the void, and also to the polishing process.…”

“…This has made rapid prototyping, which is a process of designing, constructing, and testing a component in a fast and iterative manner, a large area of research. Much work has been done in utilising additive manufacturing in the process of rapidly prototyping RF and microwave components [1][2][3][4][5]. Some have utilised 3D printers to print a plastic or resin part that is then metalised using conductive paints and epoxies or using electroplating [1,4,5].…”

“…Lost-shell casting is another method of rapid prototyping that has been studied in mechanical applications, but has not yet been used in RF and microwave applications [6]. It is a process that produces a completely metal component, but still leverages many of the advantages of the printed and metalised parts in [1,4,5] such as low material costs and more complex geometries. This process, as illustrated in Fig.…”

Lost-shell casting as a novel fabrication technique is examined, providing the durability of solid metal components with the shape flexibility of additive manufacturing. The feasibility of lost-shell casting is established for use in microwave and RF applications. A well known, standard rectangular cavity resonator design was used to validate this novel method of fabrication. Using lost-shell casting, a cavity resonator with a quality factor of 2200 was constructed. The results shown in this work confirm the validity of lost-shell casting as a novel method of rapid fabrication for completely metalised components in RF and microwave applications.

“…Over the past decades, components and devices obtained by additive technologies have begun to be actively applied and implemented [1][2][3][4]. Additive technologies have a number of advantages compared to standard ones: fewer operations, waste-free use of initial components, ease of development and optimization of products in CAD engineering programs, and high technology [5][6][7].…”

The results of a study of the complex permittivity and electromagnetic response from polymer composite materials obtained by additive technology from 3D printing filaments containing various carbon fillers are presented. New radio filaments for 3D printing with MWCNTs have been created. Investigated PLA-Conductive plastics may be used to create a shielding coating or narrowband absorbers for microwave range.

The manuscript reports on additively-manufactured (AM) coaxial-resonator-based bandpass filters (BPFs) and RF diplexers. A monolithic integration concept using stereolithography apparatus (SLA) is proposed and discussed in detail. Coupled-resonator-based synthesis alongside full-electromagnetic-based design methods is used for the design of the monolithic filters and RF diplexers. In particular, the paper discusses a new external coupling mechanism for dual-band BPFs that allow to independently control the coupling in each of the BPF passbands. Furthermore, a novel coaxial transmission line-type T-junction is proposed for the design of single- and dual-band RF diplexers. For practical validation purposes, multiple BPF and RF diplexer prototypes were designed, manufactured and tested at S- and C-band demonstrating the applicability of the proposed concept to low-cost, low-loss and low-weight RF components with complex geometrical features.
