Abstract

Through the rise in additive manufacturing increased efforts are being made toutilize these processes in traditional manufacturing. This allows for the increased complexity and expedited processing which would otherwise be unavailable to traditionalcasting operations. The objective of this paper is to compare multiple methods of additive manufacturing assistance to determine the best procedures for producing a complex part that would otherwise be unattainable through traditional casting. Two methods were studied binder jet assistance of sand casting, and poly jet assistance of investment casting. The study and comparison consisted of dimensional comparison to determine the adequacy and capability of the proposed methods, while also discussing the drawback and disadvantages experienced during production of the casting molds. The results indicate that significant improvements of time can be managed, but careful consideration to mold design must be maintained to ensure best production capability.
