Abstract Scope |
Recent advancements in Additive Manufacturing (AM) of continuous fiber composites through Fused Filament Fabrication (FFF) have enabled the development of customized high-performance composite structures. One of the key challenges in FFF is estimating the effects of process parameters on mechanical properties of the manufactured products. In this study, a coupled thermo-mechanical finite element method (FEM) is used to simulate the FFF process, and a theoretical bonding model is implemented to estimate the degree of bonding between printed layers. The model is utilized as a basis to establish the relation between processing conditions and inter-layer properties. The processing parameters such as nozzle temperature, bed temperature, layer height, and printing speed are considered as the inputs of the model while the degree of bonding between printed layers and the residual stresses are the outputs. Finally, the optimal processing parameters are determined to achieve the highest performance of the FFF method. |
