Claim:
1. A method of making a filled large-format imprinted structure, comprising: providing a substrate; locating a first curable layer over the substrate, imprinting the first curable layer, and curing the first curable layer to form a first cured layer imprinted with a first micro-cavity having a first micro-cavity width less than or equal to 20 microns; locating a curable material in the first micro-cavity and curing the curable material to form cured material in the first micro-cavity; locating a second curable layer on the first cured layer and the cured material in the first micro-cavity, imprinting the second curable layer, and curing the second curable layer to form a second cured layer imprinted with a second micro-cavity having a second micro-cavity width less than or equal to 20 microns; and locating the curable material in the second micro-cavity and curing the curable material to form cured material in the second micro-cavity, thereby forming a large-format imprinted structure.
