“…To enhance the microwave dielectric properties, the polymer is removed by sintering the ceramic/polymer composites or is reserved for a specific function (e.g., flexibility). The aforementioned examples of multi-material 3D printing of microstrip antennas would likely have additional applications in filters [ 247 , 248 , 249 ], resonators [ 234 , 250 ], and isolators [ 251 ].…”

In recent years, functional ceramic devices have become smaller, thinner, more refined, and highly integrated, which makes it difficult to realize their rapid prototyping and low-cost manufacturing using traditional processing. As an emerging technology, multi-material 3D printing offers increased complexity and greater freedom in the design of functional ceramic devices because of its unique ability to directly construct arbitrary 3D parts that incorporate multiple material constituents without an intricate process or expensive tools. Here, the latest advances in multi-material 3D printing methods are reviewed, providing a comprehensive study on 3D-printable functional ceramic materials and processes for various functional ceramic devices, including capacitors, multilayer substrates, and microstrip antennas. Furthermore, the key challenges and prospects of multi-material 3D-printed functional ceramic devices are identified, and future directions are discussed.

“…These promising technologies go beyond conventional machining to manufacture conformal [1], complex and nested parts [2]. Many technological processes are available to construct metallic devices, which can be done by direct (metallic materials [1][2][3][4][5][6][7]) or indirect (polymers or ceramic materials with metallic plating [5,[8][9][10][11][12][13][14][15]) means. The selection of the process depends on the design complexity, the available material, the cost and the robustness of the parts.…”

Increasing demand for the development of multifunction radio‐frequency‐systems requires the fabrication of complex architectures. Three‐dimensional (3D) direct metal printing direct metal laser sintering (DMLS) has the required properties to build complex and robust parts. To determine whether this technology is able to replace traditional machining methods, it needs to be extensively examined. In the present study, several waveguides operating in a wide‐frequency range, and slotted waveguide antennas with relevant details and shape, operating in the Ku‐band, were designed, machined, assessed and measured. Measurements show that the degradation of component performances are related to the fabrication strategy used. Deterministic defects were observed that make it possible to conceive ways of enhancing manufactured parts. Through this analysis, the authors demonstrate the potential of the DMLS process to construct finely detailed complex and conformal structures.

“…As depicted, alignment posts are included to facilitate the placement of SMA connectors for the input and output couplings. The proposed configuration takes advantage of the dielectric properties of ceramic materials to decrease the overall volume of the filter, while keeping the structure lightweight, especially compared with monoblock structures completely filled with ceramic material [15][16][17][18][19].…”

Transverse magnetic (TM) dielectric resonator filters are frequently affected by a poor contact in the interface between metal and ceramic walls, misalignment of the ceramic parts, and cracks due to mechanical stress. To overcome these issues, the present study proposes the development of monoblock filters fabricated by lithography‐based ceramic manufacturing. To build these structures with additive manufacturing, some geometrical changes, with respect to the classical assembly, have to be applied. The effect of these changes on the electrical performance of a stand‐alone resonator are studied. Then, a filter prototype is manufactured and measured to validate the feasibility of this approach.
