Experimental and numerical analysis of 3D-printed objects based on oriented anisotropic cells

Abstract

The use of additive manufacturing technology has grown significantly in recent years, creating new challenges for product designers. Complex designs are rarely fully described in traditional drawings or design specifications. This research aimed to address this gap by developing specifications based on the mechanical characterization of fused deposition modeling objects, focusing on their anisotropic behavior as influenced by cell structures. We used experimental design, analytical research using finite element methods, statistical analysis, and simplified numerical models to investigate the relationship between mechanical characteristics and manufacturing factors. The main effects of building attributes were examined in addition to formulating failure mechanisms and generalized elasticity. The findings allowed the creation of a simplified model to describe mechanical behavior by demonstrating the relationship between infill methods and mechanical strength.
