To fulfill their engineered purpose, resonant metamaterials require arrays of complex three-dimensional geometries composed of non-conductive dielectrics and highly conductive materials. In order to create these geometries, 3D printers must be able to facilitate the deposition of both of these materials simultaneously.This thesis explores the conductivity requirements of two common resonant metamaterial designs, and is followed by resistance measurements on 3D printed conductive conductive doped polymer. For high conductivity, hollow channels in the shape of an extended S-split ring resonator are fabricated and injected with liquid metal. This experimental work demonstrates the feasibility of 3D printing metamaterials with conductive elements.
