3D printing technology has recently been highlighted as an innovative manufacturing process. Among various 3D printing methods, a binder jetting (BJ) 3D printing is particularly known as a technology to produce the complex sand mold quickly for a casting process. However, high manufacturing cost, due to its expensive materials, needs to be lowered for more industrial applications of 3D printing. In this study, we investigated mechanical properties of sand molds with a lightweight structure for low material consumption and short process time. Our stress analysis using a computational approach revealed a structural weak point in a mesh-type lightweight design applied to the 3D-printed ceramic-polymer composite.
