Abstract: Printing orientation in polymer additive manufacturing (AM) is a crucial factor that affects both printing accuracy and the mechanical properties of the final products. Notably, printing orientation influences the interfacial bonding within printed lay-ups, thereby altering the mechanical properties to meet specific application requirements. This paper reviews studies on polyamide reinforced with carbon fibre, evaluating the impact of printing orientation, where interfacial bonding affects mechanical properties. The review shows that the common three printing orientations, 0°, 45°, and 90°, are often discussed in terms of tensile strength, fracture toughness, and electrical performance. Factors such as continuous-carbon-fibre raster angle, stacking sequence and loading direction are believed to be the main factors affecting mechanical properties. Among these, the 0° printing orientation is often associated with the highest tensile strength and stiffness due to the strong interfacial bonding between the polyamide and reinforcing carbon fibres in AM.
