Abstract

This disclosure describes systems and methods for creating porous molds using additive manufacturing processes such as three-dimensional (3D) printing. At a high level, it has been found that creating a generally porous mold, or a mold with porous regions or zones, can improve the performance of the mold and the quality of the parts created therefrom. It has further been determined that porous molds can be created using additive manufacturing techniques through manipulation of mold manufacturing parameters such as, but not limited to, layer thickness, number of perimeter layers, fill pattern, and fill density. Through variation of these manufacturing parameters, the porosity of a mold created by an additive manufacturing device, e.g., a 3D printer, can be tailored for use with molded fiber.
