Abstract

Recent advances with THz technologies have been growing significantly. The study and development of THz technology require having different components such as reflectors, lenses, splitters, and waveguides. As THz waves can penetrate a wide variety of non-conductive materials such as polymers, 3D printing can generate these components quickly and inexpensively. In this work, we present the characterization of some thermoplastic materials commonly used in 3D printing with respect to different printing specifications of infill density and layer height. We characterize the refractive index and absorption coefficient of the samples in the THz range of 0.2 to 1 THz using a THz time-domain spectrometer.
