However, the fracture resistance of 3D polymers is often reduced, which limits their use in various applications. To address this issue, this study investigates the fracture behavior of a SENT specimen using 100% of Acrylonitrile butadiene styrene (ABS) and 0.4mm thickness. The single-edge notch tension (SENT) was made under a uniaxial tensile test using MTS CRITERION MODEL 44 machine. The cohesive behavior approach used in the fracture model between the layers was tie constraint, and the type of layer's contact was defined. A comparative study of the crack propagation behavior using XFEM and experimental testing was conducted, with the experimental data analyzed using ImageJ software. The results of this study can be used to optimize 3D printing parameters and improve the mechanical properties of printed parts. © 2023 The Authors. Published by ELSEVIER B.V.

Introduction Polymers generally have several advantages, making them the first choice for the automotive industry, household appliances, etc. Hachimi et al. (2021). Among its benefits are simple shaping, lightness, chemical stability, and low cost compared to other materials Majid et al. (2020). However, they are known to have mechanical and rheological properties not yet mastered Zhu et al. (2019), which limits their use in areas requiring high precision.
