“…Three different fiber volume fractions were tested at the selected configuration (alternating with circular fiber patterns), the result showing that the highest tested fiber volume fraction (24.44%) returns the highest modulus and proportional limit. Pyl et al [29] 4N. CF layers were deposited in a unidirectional pattern and the Nylon layers were 3D-printed at 100% infill with no information on their infill pattern.…”

Fiber reinforced composites offer exceptional directional mechanical properties, and combining their advantages with the capability of 3D printing has resulted in many innovative research fronts. This review aims to summarize the methods and findings of research conducted on 3D-printed carbon fiber reinforced composites. The review is focused on commercially available printers and filaments, as their results are reproducible and the findings can be applied to functional parts. As the process parameters can be readily changed in preparation of a 3D-printed part, it has been the focus of many studies. In addition to typical composite driving factors such as fiber orientation, fiber volume fraction and stacking sequence, printing parameters such as infill density, infill pattern, nozzle speed, layer thickness, built orientation, nozzle and bed temperatures have shown to influence mechanical properties. Due to the unique advantages of 3D printing, in addition to conventional unidirectional fiber orientation, concentric fiber rings have been used to optimize the mechanical performance of a part. This review surveys the literature in 3D printing of chopped and continuous carbon fiber composites to provide a reference for the state-of-the-art efforts, existing limitations and new research frontiers.

“…Fused deposition modeling (FDM) is a type of AM extrusion‐based process wherein material is selectively dispensed via a shaped orifice or nozzle, Figure 8. FDM is being adopted for its low cost, ease of handling, and excellent processing for thermoplastics polymer such as Nylon, PLA, PET 104,105 . Among the polymers, PLA is highly demanding in AM technology because of its bio‐sustainability and stiffness 106 .…”

The global concern over the environmental protection and bio‐sustainability of plastic waste materials has prompted a vibrant search for renewable and biodegradable polymers in the academia and industrial sectors. Amidst other biopolymers, poly(lactic acid) (PLA) is identified as the most promising thermoplastic aliphatic polyester. PLA is derived from agricultural products with unique physical and mechanical properties that are comparable with the conventional petroleum‐derived polymers. Yet, some of the properties are insufficient for advanced materials applications. Rigid nanoparticles are incorporated in the PLA matrix to alleviate its properties for specific high‐performance applications. Here, we report various approaches of preparing functional PLA nanocomposites with emphasis on the strengths and weaknesses of each of the methods, as well as the achieved properties enhancement for a targeted application. Designing high‐performance PLA nanocomposite involves careful selection of the most appropriate nanofillers or combinations of nanofillers, preparation technique and processing parameters. Besides multi‐walled carbon nanotubes (CNT) and montmorillonite (MMT) that are prominent as nucleating agents to achieve high thermal and mechanical properties, other nanofillers like silver nanoparticles (AgNP) play critical roles in improving antibacterial and high‐performance properties of PLA.

“…Finding literature studies that comprehensively describe such situations is still difficult. Indeed, to the best of the authors' knowledge, the only studies that considered such an aspect were those by Mei et al [25], Pyl et al [26], and Todoroki et al [27]. Mei et al [25] evaluated the tensile properties of mixed-isotropic 3D-printed composites after hot pressing.…”

“…Mei et al [25] evaluated the tensile properties of mixed-isotropic 3D-printed composites after hot pressing. Pyl et al [26] carried out studies on the effect of mixed fiber orientations (mainly focused on investigating aspects such as specimen geometry and tab configuration for tensile testing of CCF composites), but, once again, the data are to be considered as preliminary 1 . Similar tests were carried out by Todoroki et al [27] with three fiber orientations, only for the tensile case.…”

Recent years have seen the wide diffusion of composite materials in many manufacturing fields and the rapid evolution of additive manufacturing. Lately, these technologies have been combined practically allowing the fabrication of continuous-fiber reinforced polymer parts via 3D-printing. This topic is gaining attention both in the research community and among industrial users. Because of their novelty, such manufacturing methods are, however, still not thoroughly understood, and their performance limits have not yet been fully characterized. This study aims at analyzing the mechanical resistance of components made with continuous carbon fiber (CCF) thermoplastic materials by means of fused filament fabrication (FFF), focusing on the influence of the fiber orientation on such properties. In particular, both the tensile and the bending characteristics are evaluated according to the relative test standards, in specimens with both unidirectional and mixed-isotropic configurations. The experimental findings are compared with a set of reference specimens made with a base polymer filled with chopped “short” carbon fibers, allowing one to appreciate the advantages or limitations of the different fiber arrangements.
