POLYMER BASED MOLDS AND METHODS OF MANUFACTURING THERE OF

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.

主权项

1. A method of preparing a polymeric mold for injection molding, the method comprising:
depositing, in layers, a first material having a glass transition temperature (Tg) lower than about 80° C., whereby forming a first portion of the polymeric mold; and depositing, in layers, a second material having a Tg higher than about 80° C., whereby forming a second portion of the polymeric mold, wherein the second portion at least partially covers the first portion, the second portion is thinner than the first portion and faces a cavity in the polymeric mold.
