3D printed photonic crystals with a complete bandgap in the visible range

A customized Ti-Nano resin is used to fabricate 3D photonic crystals with a complete bandgap in the visible spectrum through a nanoscale printing technique. The 3D printed and annealed titania photonic crystals show perfect reflectance within the wavelength range associated with this bandgap.
