Additive Manufacturing or Three dimensional (3D) printing is a new technology widely used to produce three-dimensional parts. 3D polymerbased printers have become easily accessible to the public. Recently, a new kind of 3D printer has been developed to manufacture printed polymer composites reinforced with continuous or short fibers. Usually, the technology used by these 3D printers is Fused Deposition Modelling (FDM). The aim of this study is to predict the mechanical properties of printed materials in Fiber-reinforced polymer (FRP) composites using a micromechanical approach. Indeed, the main idea of this approach is to characterize the effective mechanical properties from a microstructural description of the heterogeneous materials and the knowledge of the local behavior of constituents using the homogenization process. The predictions of the effective mechanical properties were confronted with experimental data obtained from the literature. The difference between the predicted and experimental values does not exceed 28.6%. The micromechanical approach is a good tool for designers to estimate the mechanical properties of fiber-reinforced 3D printed polymer composites which require specific mechanical properties.
