Evaluation of metal coating techniques up to 66 GHz and their application to additively manufactured bandpass filters

This paper presents different metal deposition techniques used for the metallization of additively manufactured plastic components. Comparison between them are presented with a focus on their use with 3D printed Ka band bandpass filters. The results, in terms of conductivity, roughness and thickness, will be analyzed and measured up to 66 GHz by a resonant cavity method. The characterized metallization techniques will be applied on different 6 th order bandpass filters working around 19 GHz.
