Abstract
A method for making a forming structure having columnar protrusions extending therefrom comprising the steps of exposing a liquid photosensitive resin to light having an activating wavelength thereby inducing partial curing of the photosensitive resin to form a monolithic slab of partially-cured photosensitive resin; and, including the step of inducing partial curing of a plurality of protrusions on the monolithic slab such that they are joined to and integral with the monolithic slab. The method can further comprise the step of laser etching a plurality of apertures through the forming structure.
