Abstract: Carbon Fiber Reinforced Polymer (CFRP) composites have been used in additive manufacturing (AM) to increase the stiffness and strength of the parts. CFRP produced by AM is being considered for tooling applications. In AM, short carbon fibers are aligned along the deposition direction. However, it results in anisotropic thermal properties that affect the heat transfer and warpage of the final part. In this study, three male molds with different infill patterns were considered based on the slicing software for the extrusion deposition fabrication-additive manufacturing (EDF-AM) process. These include (a) 0°: infill pattern along the printing direction; (b) 90°: infill pattern perpendicular to the printing direction; (c) 0°/90°: alternate layers along and perpendicular directions. Finite Element Analysis (FEA) was conducted to understand the effect of infill pattern on a heat propagation. The results show that the directionality of the infill affects the heating performance.
