“…Finally, it is worth noting that other approaches could be implemented to reduce the void content, such as printing inside at low pressure conditions inside a vacuum chamber [ 55 ], using a material preheating system [ 56 ], a layer post-compaction stage [ 57 , 58 ] or a combination of the two [ 59 , 60 ]. This last method is usually adopted in Automated Fiber Placement (AFP) to improve material consolidation [ 61 ].…”

The development of 3D printed composites showing increased stiffness and strength thanks to the use of continuous carbon fibers has offered new prospects for Fused Filament Fabrication (FFF) technique. This work aims to investigate the microstructure and mechanical properties of 3D printed CCF/PA composites with various layups, and also to apply predictive models. The mechanical properties of the printed parts were directly related to the adopted laminate layup as well as to the microstructure and defects induced by the FFF process. The highest stiffness and strength were reported for longitudinal composites, where the fibers are unidirectionally aligned in the loading direction. In addition, it was found that the reduction in tensile properties obtained for cross-ply and quasi-isotropic laminate layups can be described by using the Angle Minus Longitudinal. A step-like failure with extensive fibers breakage and pull-out was observed for the longitudinal composites. By contrast, the rupture mode of the quasi-isotropic laminates mainly exhibited debonding between beads. Moreover, the predictions obtained using the Volume Average Stiffness method and Classical Laminate Theory were in good agreement with the tensile test results. This work could help engineers to design complex laminates with specific mechanical requirements by tailoring the orientation of continuous carbon fibers.

“…Due to the continuous fiber-reinforced thermoplastic composites (CFRTC) have the advantages of high strength, high modulus, lightweight, high thermal stability, designability, etc [5][6][7]. CFRTC based FFF printing can provide better strength and stiffness and has become a vital method to improve the performance of 3D printing, which is widely used in automotive, electronics, aerospace, medical, and other industries.…”

In order to improve the strength and surface quality of fiber-reinforced composite 3D printed parts and reduce the overfilling and underfilling caused by the manufacturing process of molten filaments under continuous paths, a co-extrusion control and optimization method based on matrix adaptive feeding with printing speed and deposition spacing is proposed in this paper. The method not only achieves surface void filling under different paths, but also reduces the porosity of the printed parts and improves the strength of the printed parts by adjusting the matrix extrusion under different deposition spacings. Compared with the common co-extruded model, the tensile strength is increased by 18% , the bending strength is increased by 23.4% and the porosity decreased by 54.4%. The proposed method is applicable to models with arbitrary continuous infill patterns and improves the quality of fiber-reinforced printed parts, especially to avoid structural failure due to uneven filling.
