Abstract
Methods of manufacturing a panel and resulting panels include a plurality of microholes arranged in a pattern and filled with light transmissive polymeric material. The light transmissive polymeric material occludes the microholes and is set, or cured, by exposure to an energy source using at least two discrete exposure periods separated by an idle or rest period.

A method of manufacturing a panel, comprising:
- occluding a plurality of microholes arranged in a pattern with a light transmissive polymeric material, the light transmissive polymeric material being in a workable state and the plurality of microholes extending from a first opening in a first surface of a substantially planar area of the panel to a second opening in a second surface of the substantially planar area opposite to the first surface, each of the first opening and the second opening having a diameter smaller than a thickness of the substantially planar area;
- and
- setting the light transmissive polymeric material occluding the plurality of microholes from the workable state to a set state in which the light transmissive polymeric material is secured to an interior surface of the plurality of microholes by exposing the visible light transmissive polymeric material to a source for a first exposure period, providing a first idle interval wherein the light transmissive polymeric material is not exposed to the source after the first exposure period and exposing the light transmissive polymeric material to the source for a second exposure period after the first idle interval.
A panel, comprising:
- a substantially planar portion including a first planar surface and a second planar surface opposed to the first planar surface;
- a plurality of microholes passing from the first planar surface to the second planar surface, each microhole communicating with first and second apertures defined in the respective planar surfaces and having an internal surface therebetween;
- and
- a light transmissive polymeric material disposed within each microhole, the light transmissive polymeric material having a first outer surface substantially coplanar with the first planar surface of the body, a second outer surface opposed to the first outer surface and a central body disposed therebetween;
- and
- wherein the central body of the light transmissive polymeric material has a outer central surface in contacting engagement with the internal surface and wherein the light transmissive polymeric material has a polymeric chain wherein at least 5% of components are derived from UV curable epoxy acrylate oligomers exposed to at least two periods of UV exposure separated by a rest interval.
