    摘要: Polymer-based molds and methods of manufacturing are described. The method includes depositing two or more layers of a first material having a glass transition temperature (Tg) lower than about 70° C., in order to form a first portion of the mold and then depositing two or more layers of a second material having a Tg higher than about 80° C. to form a second portion of the mold. The method may further include depositing two or more layers of a material having a Tg lower than about 70° C. forming a third portion of the mold to cover the second portion.
