“…As printing speed rises, the time that filament stays in the nozzle decreases, reducing pressure and impregnation time. In most studies, increasing printing speed resulted in a loss in mechanical characteristics (e.g., see Chen et al 47 ), whereas in others, the influence of print speed on mechanical properties was shown to be insignificant.…”

The main objective of this study is to review existing research on the application of fused deposition modeling (FDM) for 3D printing of continuous fiber reinforced composites (CFRCs). An overview of additive manufacturing technology production techniques is provided first, followed by a look into FDM technology. The articles on CFRC printing were then summarized. The type of reinforcing material and matrix utilized, the studied parameters, the mechanical tests, and their results, are all listed. Various pre-processing, processing, and post-processing conditions, as well as their impact on CFRC mechanical properties, were also discussed. Finally, several study gaps were identified and suggestions for further research were presented.

“…PLA has been con rmed to be safe for all food packaging applications and has been listed as GRAS by the US Food and Drug Administration (FDA) [8]. It was widely used in medicine [9,10], textile industry [11], food packaging [12,13], 3D printing and other elds [14,15] rely on its advantages of non-toxic, biodegradability, good biocompatibility, excellent mechanical property and processing characteristics [16]. However, its application scope was limited due to the disadvantages of high price and brittleness of pure PLA products.…”

Pea dietary fiber (PDF) was filled into polylactic acid (PLA) to prepare PLA/PDF composites with different PDF contents (0%, 2.50%, 5.00%, 7.50%, 10.00%) by hot melt extrusion. The thermodynamic properties, microstructure, degradability of PLA/PDF composites were investigated. Results showed that the continuity, smoothness and mechanical properties of the PLA material structure were improved, which was attributed to the defects of the PLA material structure were significantly compensated by the appropriate amount (≤ 5.00%) of PDF. The degradation experiment exhibited that the degradation rate of PLA could be significantly improved by using PDF as filler. The degradation rate of 10.00% PLA/PDF composite at the end of soil, aqueous soil biodegradation and in vitro degradation experiments was 134.09%, 210.00% and 500.00% higher than that of PLA material containing 0% PDF, respectively. In summary, PLA/PDF composite containing 5.00% PDF had the optimum comprehensive properties in terms of smooth surface, good mechanical properties and excellent degradability. That possessed huge market potential in the field of material processing. This study combined materials science with food science, which broadened the new research ideas in the field of polylactic acid modification and PDF application.

A dual-nozzle 3D printing technique was proposed to prepare continuous glass fiber reinforced PA6 (CGF/PA6) composites with sandwich structure. Short glass fiber reinforced PA6 filament was used for printing the surface layer and CGF/PA6 filament was used for inner part to provide high-mechanical performance. Morphology of CGF/PA6 filament and the properties of printed composites samples were investigated. Printing process parameters were systematically optimized. The results showed that when CGF/PA6 part thickness of the composites samples was 2.8 mm, the flexural strength and flexural modulus, notched impact strength and interlaminar shear strength of the printed products can reach 275.4 MPa, 10.8 GPa, 168.2 kJ/m 2 , and 26.5 MPa, respectively. The dual-nozzle 3D printing strategy in this work was of great significance for the precision fabrication of continuous fiber reinforced thermoplastic composites (CFRTPC), which can be widely used in aerospace, automotive, wind turbine blades, shipbuilding, and other industrial fields due to their excellent mechanical properties and ability to resist vibration and corrosion.
