This study examines Continuous Fiber Fabrication (CFF), a special material extrusion method capable of manufacturing composites with additive manufacturing (AM). CFF, developed by Markforged, is an alternative method of manufacturing composites by combining material extrusion and fiber reinforcement technologies. Finite Element Analysis (FEA) can be considered as a way to evaluate mechanical responses under different loading conditions. However, there are disparities in the current literature, and this leads to the development of an FEA technique for CFF parts. White Nylon and Carbon Fiber are selected as materials for the study, and material characterization tests are performed first to obtain FEA input. The samples are then designed and manufactured, and later tested with tensile, bending, and eccentric loadings. Finally, corresponding FEA simulations, which are based on the force and displacement for elastic behavior, are solved to compare the results with the experiments. For small displacements, the results are in good agreement, but for greater plastic deformations, there are discrepancies. Although numerous studies in the current state of the art focus on FEA modeling of CFF parts, this work distinguishes itself by integrating simulations and experimental tests under different loading conditions, providing a unique comparison that enhances the understanding of the elastic behavior of CFF parts.
