Résumé : The additive manufacturing process known as Fused Deposition Modeling (FDM) is distinguished by numerous parameters to be set. These parameters determine the mechanical properties and the overall quality of the printed parts. Among these parameters, we are interested in the filament deposition temperature. Indeed, during the systematic printing of each layer, the filaments that compose it undergo fusion, both inside the layer itself and between successive layers. The quality of this welding process significantly influences the resistance to crack propagation, between filaments of the same layer and/or between superimposed layers. This article focuses on the study of the impact of deposition temperature on the resistance to crack propagation in structures created by FDM. An analysis based on the J-Integral approach is developed.
