A method of fabricating a structure includes disposing a liquid photoreactive composition on a substrate, exposing a portion of the liquid photoreactive composition to laser light of sufficient intensity and wavelength to cause polymerization via two-photon excitation of the two-photon sensitizer and polymerization of a portion of the liquid photoreactive composition thereby providing an exposed composition; and developing the exposed composition to provide the structure. The liquid composition includes: at least one cationically polymerizable polyepoxide; at least one compound comprising free-radically polymerizable groups; an effective amount of a two-photon photoinitiator system, wherein the weight ratio of component (a) to component (b) is from 25:75 to 75:25, inclusive. The two-photon photoinitiator system includes a two-photon sensitizer and an aromatic onium salt. The liquid photoreactive composition may contain less than about one percent by weight of organic solvent.
