CREATION OF INJECTION MOLDS VIA ADDITIVE MANUFACTURING

Abstract:

Methods of manufacturing an injection mold component are provided. The methods include printing a plurality of layers of a material into a near net shape mold of the injection mold component. The printing includes forming each layer in the plurality of layers upon another layer in the plurality of layers such that a volumetric part cavity is positioned between the plurality of layers. The volumetric part cavity corresponds to a coarse model of at least a portion of an injection moldable part. The method further includes removing material from the plurality of layers, whereby the volumetric part cavity expands to correspond to a precise model of the at least a portion of the injection moldable part and to form the injection mold component.
