Mechanical anisotropy and fracture mode of binder jetting 3D printed calcium sulfate moldings

Binder jet three-dimensional (3D) printing has been extensively developed since the early 1990s and is widely applied in various industrial fields. Binder jetting 3D-printed products have anisotropic mechanical properties; however, no study has provided a systematic explanation of this mechanism. Herein, we propose that the crystal lattice model based on the crystallographic logic can explain the mechanical anisotropy and fracture mode of...
