Resumen: This work carries out an in-depth analysis of the influence of the manufacturing parameters on the behavior of a material with better mechanical properties than the usual ones, PLA and ABS, such as PETG (Polyethylene terephthalate with glycol), and the carbon fiber reinforced version. This study performs the experi-mental characterization on interlaminar fracture of this material, with the aim of acquiring a better knowledge of it, but also generates a model of material behavior that takes into account the effects on the properties of the printing profile, in other words, of the selected manufacturing parameters. In order to achieve such objective, a finite element numerical model has been developed, using cohesive elements to simulate the contact zones between layers. Also, failure and degradation modes of the material would be enclosed in the model behavior. A bilinear behavior model is used to simulate the response of the interlaminar zones. The properties of the model, as well as its subsequent adjustment, are supported from the results obtained in the experimental phase. As a final result of the work, the authors propose a series of graphs that allow the selection of these properties to be used in the model, depending on the manufacturing parameters selected for a future application.
