Abstract
Anisotropy in the mechanical properties of rock is often attributed to layering or mineral texture. Additive manufacturing enabled control of the mineral structure in printed rocks. This work explores the effects of layers and mineral texture on fracture evolution. Three-point bending and unconfined compressive strength tests were performed on the 3D printed gypsum samples with a Deben CT5000 in-situ stage inside a Zeiss Xradia 510 X-ray microscope. Visual interpretation of how the materials changed under different loading conditions was provided to confirm the dominant role of mineral texture orientation and layer orientation on fracture formation
