Recent advances in rapid prototyping technologies have resulted in build-resolutions that are now on the scales required for direct fabrication of photonic structures in the gigahertz (GHz) and terahertz (THz) regimes. To demonstrate this capability, we have fabricated several structures with 3D bandgaps in these spectral regions. Characterization of the transmission properties of these structures confirms the build accuracy of this fabrication method. The result is a rapid and inexpensive fabrication technique that can be utilized to create a variety of interesting photonic structures in the GHz and THz. We present the results of our characterization experiments and discuss our current efforts in extending the technique to fabrication of other structure types.
