Print! Place! Perform!: Additively Manufactured Surface-Mounted Bandpass Filter in X Band

The advance of 3D-printing technology over the last decade makes additive manufacturing not only attractive for rapid prototyping, but also provides it as a trendsetting approach to realize conventional as well as sophisticated functional microwave and millimeter-wave passive components. It has proven its ability to replicate conventional waveguides with a comparable electrical performance

. In this way, low-cost, lightweight waveguides with customized dimensions and shapes are realizable. Moreover, 3D printing enables the implementation of unconventional complex-shaped waveguide components, such as filters

, whose design is restricted by the engineer’s creativity rather than by limitations of conventional fabrication techniques.
