- Abstract
- In this paper, we investigated the process variable effects on the damage and deformational behavior of fused deposition modeling (FDM) three-dimensional (3D)-printed specimens by performing tensile tests and inverse identification analyses. A characterization of the effects of different parametric variations of 3D-printed specimens on fracture properties are a matter of considerable significance that are often overlooked. By combining the infill density and the layer thickness options that are available in the 3D printer machine, six groups with different structural configurations can be obtained. The data and images obtained from experiments are employed to investigate the failure mechanism of 3D-printed specimens and demonstrate the relationship that exists between structural variations and fracture mechanical properties. On the basis of experimental results, a Gurson-type porous plasticity model was used within a 3D continuum finite element model to characterize the process–damage parameter relationship through an inverse identification process.
