Abstract
Abstract This study investigates the influence of infill patterns and densities on crack propagation behavior in additive manufactured parts. Through three-point bending tests, force–displacement data were obtained for specimens with different infill patterns, densities, and crack sizes. The results demonstrate that infill density significantly affects the mechanical properties and fracture characteristics of the parts. Higher infill densities result in increased strength but reduced tolerance for deformation, leading to a more abrupt failure mode. The findings highlight the importance of carefully selecting the infill pattern and density to optimize the mechanical performance of 3D-printed parts. Understanding these relationships is crucial for designing robust and reliable structures for various applications in additive manufacturing.
