The 3D printing process used in our study was FDM with a PLA substance using the Cubic-Subdivision Infill Pattern at 20 percent infill density. This process is known for its high precision and accuracy, which was important for ensuring the consistency and repeatability of the samples. The process also allowed for the creation of complex geometries and structures, including the predeflected crack and small deflected region present in the interface, which were key features of the simulation models.
