There is an economical and scientific drive for the fabrication of synthetic rock cores for study in the geological sector. Through additive manufacturing, sandstone can be fabricated using a powder bed system, where layers of sand are printed upon with a binder jet print head. With additive manufacturing, extrinsic defects caused by coring can be avoided and internal defects, such as voids and fractures, can be placed with precision during fabrication. However, although the dimensions and features of the synthetic rock can be controlled, the unconfined compressive strength of the samples is less than natural sandstone due to the polymer binder used during fabrication. The following paper will outline the current printing procedure, capabilities and limitations of the printing process.
