Abstract

The present invention is directed to a method of forming a mold for use in making molded articles having a plurality of microprojections. Additionally, the present invention provides a method of forming a molded article having a plurality of microprojections. In one aspect, a mold workpiece is provided, a tool having a tip with a shape corresponding to the microprojection, wherein the hardness of the tool is greater than that of the mold workpiece, is pressed into the mold workpiece and removed, thereby creating a mold with a microprojection cavity suitable for use in making the molded article.
