Effects of Cutting Planes on Filter Performance of FDM 3D-Printed X-Band Waveguide Filters

In this paper, the impact of E-plane and H-plane cuts on filter performance of 3D-printed waveguide filters manufactured with fused deposition modeling (FDM) is examined. The employed manufacturing procedure consists of FDM 3D-printing and the subsequent electroplating process. A number of samples in both configurations are fabricated and surveyed. The measurement results are quantified and a comparison is conducted. Finally, the differing filter behaviors are discussed.
