This work presents the characterization of various 3D printing materials for their use in the design of high-frequency devices. These materials not only act as structural supports but also as elements whose dielectric properties and geometry modify the behavior of the designed network. Therefore, precise extraction of the dielectric characteristics that these materials present is very important. For this study, 3D-printed parallelepipeds are used to be inserted into the interior volume of two rectangular waveguide sections, specifically WR137 and WR90 with lengths of 51 [mm]. In the process of measuring the S-parameters in these waveguide sections, a Vector Network Analyzer (VNA) is used to evaluate and characterize these materials. Two waveguide sections are added to the ends of the test line, which serve as a transition from the coaxial cables of the VNA to the waveguide. This transition structure includes a dipole that connects the ends of the waveguide with the coaxial cables, allowing the signal transition inside the waveguide. The obtained measurements are subsequently compared with electromagnetic simulations of the corresponding structures, aiming to achieve a complete agreement between the obtained measurements and the simulations by adjusting the properties of the materials. The results reveal important information about the behavior of 3D printing materials in high-frequency applications. Surprisingly, it can be observed that there is not a significant difference in terms of performance between materials specifically designed for high-frequency devices and common and more affordable materials such as PLA and ABS.
