This paper demonstrates the use of a ceramic-based stereolithography additive manufacturing process in the fabrication of higher-order mode dielectric resonators. In this work, dielectric resonators with concentric disks around a combline rod structure are 3D-printed using alumina. The integration of the concentric disks for use of the TE 112 mode allows for a more compact cavity structure and a higher unloaded quality factor when compared to a simple dielectric combline resonator with a similar S-parameter response. The achievable improvements in quality factor for the TE 112 -mode resonators utilising concentric disks are compared through simulations and experimental results. The measured results demonstrate an increased average in the unloaded quality factor of Q u ≈ 2172 which is approximately 44%. Additionally, the application of the 3D-printed resonators is further demonstrated in a TE 112 singlet, doublet, and dualmode filter configuration.
