Continuous fiber-reinforced thermoplastic (CFRTP) composites are increasingly used in aviation, automotive, transportation, and medical applications because of their high strength and low weight properties. Manufacturing these composites with additive manufacturing has drawn the attention of researchers, especially since 2015. Although there are many different approaches to printing CFRTPs, the usage of prepreg filament yields the highest mechanical properties. Therefore, in this study, a polymer impregnation line was used to impregnate 3K carbon fiber support material with polylactic acid (PLA) matrix to obtain CFRTP filament. Obtained filament has a 0.6 mm diameter corresponding to a 41% fiber volume fraction. This filament is then used in a 3D printer based upon fused deposition modeling (FDM) to print test samples. The additional infrared heat source was used while printing to increase the interlaminar bonding. Effects of this process were investigated using three-point bending tests. Without an infrared heater, the obtained strength was around 408 MPa. Using an infrared heater increased this value by 14.12% and achieved 465.66 MPa of bending strength.
