This work extends on previous demonstrations of this process in plating stereolithography (SLA)-printed resin waveguide parts by investigating number of plating rounds, reaction temperature, and plastic base. It is found that less than 1.5 dB/m attenuation is achievable in WR42 waveguide using white SLA plastic and silver plating, comparing favorably with the 10 dB/m achieved by printing the same part using Ti64 powder bed fusion. This process improvement is further demonstrated using waveguide power dividers, slow wave delay sections, and rectangular horn antennas.en© 2023 IEEE.
