3D-printer materials are becoming increasingly more appealing also for high frequency applications. Thus, the electromagnetic characterization of these materials is an important step in order to evaluate their applicability in new technological devices. We present a measurement method for the loss tangent evaluation based on a dielectric loaded resonator (DR). Comparing the quality factor Q of the DR with a disk-shaped sample placed on a DR base with Q obtained when the sample is substituted with an air gap, allows a reliable loss tangent determination.
