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.
Claims20
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 light transmissive polymeric material to an energy source for a first exposure period, providing a first idle interval wherein the light transmissive polymeric material is not exposed to the energy source after the first exposure period and exposing the light transmissive polymeric material to the energy source for a second exposure period after the first idle interval;
- and
- wherein a length of the first idle interval is such that the light transmissive polymeric material in the set state transmits light through the plurality of microholes with a uniformity substantially similar to a uniformity that the light transmissive polymeric material in the workable state transmits light through the plurality of microholes.

- 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 one of the first surface or the second surface to an energy source for a first exposure period;
- providing a first idle interval wherein neither the first surface nor the second surface is exposed to the energy source;
- and
- exposing the one of the first surface or the second surface to the energy source for a second exposure period after the first idle interval, wherein the first idle interval begins at an end of the first exposure period and ends at a beginning of the second exposure period such that the first exposure period, the first idle interval and the second exposure period form a continuous time period.
