Abstract
A method for rapidly forming a cast tool adapted for plastic molding includes preparing a uniform mixture of a castable material. A pattern is provided for a desired object to be formed by molding. The castable mixture is applied to the pattern. A continuous structure is cast within the castable material. The castable material is then cured to form a tool.
