Claim:
1. A system comprising: a laser system programmed to form a modified wax model of a turbomachinery part including at least one surface texture element absent from a preliminary wax casting model though laser ablation, wherein the the laser ablation includes applying an ultra-short-pulse laser to the preliminary wax casting model to directly vaporize a portion of the preliminary wax casting model, forming the at least one surface texture element, wherein the surface texture element includes a microchannel having an aspect ratio of approximately 1 to approximately 10; an imaging system for scanning the modified wax model of the turbomachinery part to image the at least one surface texture element after the performing of the laser ablation; a coating system for coating the modified wax model of the turbomachinery part to form a mold shape around the modified wax model of the turbomachinery part, and removing the modified wax model of the turbomachinery part to leave a casting mold including the at least one surface texture element; and a casting system for casting a shape from a casting material using the casting mold having the at least one surface texture element.
