In this paper we demonstrate the terahertz propagation in hollow core fiber with negative curvature core, manufactured through rapid prototyping technique using low cost 3D printer. The fiber was numerically and experimentally characterized using finite element software and a terahertz time domain spectrometer (THz-TDS). The results indicate that the fiber guides at least until 1.1 THz, covering spectral range with extremely high loss materials. The guidance is supported by antiresonant effect. The fiber was printed with low resolution 3D printer leading to hollow-core structure with several surface modes.
