1. A method for forming a micropillar array for an evaporative heat exchanger, the method comprises:
selecting a preliminary shape for a micropillar;
determining a droplet shape that is generated by the preliminary shape;
generating at least one curve that defines the droplet shape;
performing an evaporative simulation based on the curve;
selecting a final shape for the micropillar based on the evaporative simulation;
generating a build file including the final shape for the micropillar selected based on the evaporative simulation; and
operating a fabrication device in accordance with the selected final shape for the micropillar and the build file to fabricate an array of micropillars, wherein the array of micropillars includes at least one micropillar having the final shape for the micropillar, wherein the final shape for the micropillar is a cross-sectional shape of the micropillar.
