Additive manufacturing (AM) is a promising way to produce complex structures by adding layers. AM arises great interest both in industrial and academic sectors to develop new advanced structured materials. To benefit from its advantages, it is important to accurately characterize the mechanical properties of the obtained structures in order to ensure their integrity during operation. It becomes important to characterize these structures at the local scale (micron and/or the nanometer scale). In the specific case of polymeric materials produced by Fused Deposition Modeling (FDM), the comprehension of the mechanical behavior between adjacent layers during deformation can help to improve mechanical properties. However, few studies in the literature have focused on implementing approaches to characterize local strains at the surface of these materials. In this study, an original approach based on the use of a speckle pattern with particles average Citation: Djouda, J.
