Fused deposition modeling (FDM) is one of the most popular additive manufacturing (AM) processes that works based on the layer-by-layer buildup of a 3D modeled part from polymers or fiber-reinforced polymer materials. In recent years, extensive research has been done to characterize the mechanical properties of FDM produced parts using classical laminate theory (CLT). However, considering the limitation of micromechanics approach to simple unit cells, there is a need to explore different techniques to alleviate those limitations. Taking into account the periodicity and multiscale nature of FDM infill patterns, one such technique is the asymptotic homogenization method used in this study to find mechanical properties. Moreover, the input of homogenized properties in CLT is discussed. Finally, both homogenization and CLT results are compared with experimental results.
