    摘要： A multi-material mold and a method of constructing a multi-material mold for injection molding using additive manufacturing comprises defining a structure of the mold; and defining at least two sub-regions, associating the sub-regions with respective specific materials and printing the sub-regions with the specific material. The sub-regions may include an internal sub-region that allows dissipation of heat accumulating during use of the mold, where the specific material is heat conductive; an embedded heat sink sub-region for conducting heat away from the internal sub-region allowing dissipation, where the specific material is relatively non-conductive mold material embedded with lines or layers of relatively heat-conductive material; a sub-region resistant to abrasion, where the specific material is an abrasion-resistant polymer; a sub-region resistant to breaking under process conditions, where the specific material is a high toughness and high Tg polymer or a digital material and a sub-region of flexible material for sealing and releasing.
