Metallodielectric photonic crystals with periodic arrangements of dielectric ceramics and conductive metals were fabricated in submillimeter–order sizes to control millimeter waves. Polyester resins with titania particle dispersions were injected into inverse sphere structures with body‐ and face‐centered cubic lattices formed by laser scanning stereolithography. The transmission properties of the millimeter waves passing through the crystals were measured using time domain spectroscopy and simulated using transmission line modeling. Photonic band gaps could be opened for all crystal directions to totally reflect the incident waves by spatial Bragg diffraction. Modified crystals with compressed lattice spacings were processed to modulate the diffraction wavelengths.
