摘要

In this paper a process of a direct mold production by Rapid Prototyping (RP) method is presented for casting metal (bronze) parts. According to this method object's geometry was captured in electronic form by Computer Tomography (CT). The metal fluid flow during casting was simulated by suitable FEM software and information about the effects of fluid flow, heat transfer and related forces on immersed and surrounding components was used for redesign molds. Molds were manufactured in a 3D printer using special plastic powder. The method was tested in casting of archaeological findings replicas with complicated geometry. Finally the casted parts were inspected, regarding their form accuracy in comparison to the prototypes.
