In recent years, the field of additive manufacturing has evolved rapidly in terms of objects' complexity, materials, manufacturing times, components already assembled, etc. The objective of the project is to characterize components manufactured by fused deposition modeling (FDM) that can be influenced by several parameters. Herein, the most important ones are studied by a combination of simulation with MSC and DIGIMAT software following two different approaches: macro-scale and material's mesostructure-based analysis. The finite element method (FEM) will be used for the validation, and for the experimental data, they will be used both values of stress-strain from the literature and from laboratory tests.
