Three-dimensional sand printing (3DSP) is an emerging additive manufacturing (AM) process with the potential to produce complex casting molds that were previously unfeasible with traditional methods. However, the casting volume is limited due to the size constraints of 3DSP printing. This study presents a modular, joinery-based, self-interlocking 3DSP casting mold system designed to overcome these limitations while minimizing traditional casting mold restraints. The efficacy of the mold system was illustrated through the metalcasting of an A356.2 aluminum alloy cylinder using varying parameterizations of a dovetail joint design. Relevant casting metrics, including volume, percent volume of excess material (mold flash), and volumetric shrinkage, were statistically analyzed to assess the impact of joinery design on the quality and characteristics of both the 3DSP molds and the resulting metalcastings. The analyses revealed that the joint design parameters—specifically the angle of the mold-mating faces and their length—had minimal effects on the volume of flash, shrinkage, and density. Conversely, the joint design significantly influenced the ease of assembly. The outcomes from this study will facilitate the development of larger-than-printable, complex, multi-piece self-interlocking casting molds without degrading the quality of the resulting metalcastings.
