Casting of complex structures in aluminum using gypsum molds produced via binder jetting

Purpose The purpose of present paper is to enlarge the knowledge about performance gypsum powder realize complex molds or cores for aluminum casting. Design/methodology/approach research was divided into two activities: simple; and complex-part production capability. In simple-part step, minimum mold thickness that would withstand casting process. authors first investigated removability as a function geometry complexity then binder jetting evaluated case lattice-structure fabrication. Findings All geometries tested process demonstrating benefits in terms part design; however, suffers all typical defect misrun, porosity cold shut. Originality/value results found this improve related additive manufacturing application industrial environment particular technology rapid approach.
