A Fabrication and characterization of sand-casting mold using conventional and additive manufacturing process - A Review

Abstract: This article compares techniques to manufacturing cast molds by conventional sand-casting and 3-D printing procedures. The techniques were evaluated in terms of lighter weight, tensile strength, hardness, and microstructure. The results demonstrate that there are several advantages to using 3-D printing techniques in mold fabrication. The molds produced by 3-D printing offers a full-size sand saving, tensile strength, hardness, and microstructure.
