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.

“…In addition, the determination of print conditions is crucial to avoid composite printing instabilities. The common instabilities in continuous fiber printing were reported in the author's previous work (Mosleh et al, 2021). A low ratio of fiber length in comparison to polymeric filament length (L fiber /L filament ) makes fiber tearing and fiber fuzzing, while the high ratio of (L fiber /L filament ) causes fiber twisting.…”

“…The flat tip presses prepreg tow and polymeric filament on the build platform, and fused polymer penetrates to fiber bundles. Also, the nozzle’s internal wall was covered by a Teflon coating to decrease friction between prepreg glass tow and nozzle wall and avoid premature melting of ABS polymer (Mosleh et al , 2021). In addition, the use of ABS filaments with lower diameters than commercial filaments is also useful in reducing friction with the nozzle wall.…”

Purpose In this paper, continuous glass tow preg-reinforced acrylonitrile butadiene styrene (ABS) composites were fabricated by using a 3D printing method, and the purpose of this study is the investigation of the fiber preimpregnation effect on the mechanical behavior of these composites. In addition, a simple theoretical approach (mixture law), which considers the elastic behavior of reinforced composites and a numerical simulation method based on finite element method (FEM), was used to predict the tensile stress–strain behavior of ABS/glass tow preg composites in the elastic region. Design/methodology/approach Different groups of preimpregnated glass tows with various ABS amounts (named 2%, 10%, 20% and 30%) were prepared by the solution impregnation method. Then, preimpregnated glass tows (prepregs or tow-pregs) were fed into the printer head along with the polymeric ABS filament to print the composites. The tensile, flexural and short beam tests were conducted to evaluate the mechanical properties of the printed composites. Findings The first result of using tow-pregs instead of dry tows in continuous fiber 3D printing is much easier printing, printability improvement and the possibility of printing layers with low thickness, which can further increase the mechanical properties. The mechanical test results showed all of the glass prepregs improve strength and modulus in the tensile, three-point bending and short beam tests compared with neat ABS specimens, but statistical analysis showed that ABS weight percentage in the prepregs had no significant effect on the mechanical strength of composites except for the tensile modulus. Samples containing 2%-prepreg (minimum ABS amount in the tow-pregs) showed a significant improvement in tensile modulus. In the simulation section, good agreement is obtained between the model predictions and experimental tensile results. The results show that an acceptable deviation (14%) exists between the experimental and predicted value of elastic modulus by the numerical model. Originality/value To the best of the authors’ knowledge, this is the first study showing the effects of ABS weight percentage in prepregs on the mechanical properties of 3D printed continuous fiber-reinforced composites and predicting the mechanical behavior of 3D printed composites by numerical simulation method.

“…The most widely employed technique under this process principle is fused deposition modeling (FDM) [37] or fused filament fabrication (FFF). [38][39][40][41] It works with the externally applied pressure on a nozzle containing viscoelastic material, which can directly apply the substance with a predetermined pathway using a computer modeling tool, referred to as direct ink writing (DIW). [42,43] Extrusionbased techniques are advantageous in easy operation and precise printing of complicated geometries with varying structures despite requiring a material with specific characteristics like printing temperature.…”

The latest developments in smart systems for improved human lives with advanced biomedical devices have evolved out of multi‐disciplinary scientific studies, including medicine, biology, material sciences, design, manufacturing, artificial intelligence, microelectronics, and so forth. The growth of such intelligent systems is primarily possible with innovative materials, which demonstrate the response to various external stimuli like temperature, heat, moisture, light, electromagnetic field, and chemical alteration. Such materials have been recently fabricated using different additive manufacturing techniques to devise personalized unique, complex, and novel structures that can adjust to external conditions over time and are specifically attributed to 4D printing. Novel materials that can further improve such systems continued to be explored and employed. This review paper investigates the additive manufacturing of functional polymer nanocomposites, which offer compliant structures with flexible manufacturing processes with high strength, low cost, and long‐term stability. This study aims to deliver a comprehensive and deep understanding of the latest developments in materials, design, manufacturing, fundamental mechanisms involved, and future possibilities in this area of research.
