“…Furthermore, it has been noted that a 10% volume fraction of CF in the PP matrix illustrated better surface quality, good extrudability and less agglomeration of material, better printability, strong adhesion with the matrix and good dispersion of fibres compared to a 15% and 20% volume fraction. Similar findings were observed by Liao et al [ 154 ] when they conducted a study using a CF/PA 12 composite printed with the FDM process. The flexural, tensile and impact properties of the PA12 print specimen were notably enhanced by adding 10 wt% of CF to it.…”

Fused deposition modelling (FDM) is one of the fastest-growing additive manufacturing methods used in printing fibre-reinforced composites (FRC). The performances of the resulting printed parts are limited compared to those by other manufacturing methods due to their inherent defects. Hence, the effort to develop treatment methods to overcome these drawbacks has accelerated during the past few years. The main focus of this study is to review the impact of those defects on the mechanical performance of FRC and therefore to discuss the available treatment methods to eliminate or minimize them in order to enhance the functional properties of the printed parts. As FRC is a combination of polymer matrix material and continuous or short reinforcing fibres, this review will thoroughly discuss both thermoplastic polymers and FRCs printed via FDM technology, including the effect of printing parameters such as layer thickness, infill pattern, raster angle and fibre orientation. The most common defects on printed parts, in particular, the void formation, surface roughness and poor bonding between fibre and matrix, are explored. An inclusive discussion on the effectiveness of chemical, laser, heat and ultrasound treatments to minimize these drawbacks is provided by this review.

“…[13b] This phenomenon generally occurs due to poor wettability of fiber with thermoplastic, which leads to poor fiber–matrix interface. Moreover, higher loading causes viscosity to increase and flowability to decrease, thus causing processability issues such as nozzle clogging (≈40 wt%). [13b,31] Surfactants and plasticizers can be added to improve fiber‐to‐matrix bonding and the processability of the material.…”

Additive manufacturing (AM) has brought about a revolution in the way we can manufacture complex products with customized features. AM has paved its way in the application areas ranging from aerospace, automotive, consumer to biomedical. AM of composites has attracted special attention due to its promise in improving, modifying, and diversifying the properties of generic materials through introducing reinforcements. This review provides a detailed landscape of fiber‐reinforced composites processed via AM techniques. Different AM processes, various material formulations, and strengths and drawbacks of AM methods are discussed. Emphasis is paid to AM techniques focusing on continuous fibers, as they hold the promise of becoming the next‐generation composite fabrication methodology. The article also tries to identify the potential of AM technology for fiber‐reinforced composites and delves into challenges facing the area.

“…These pure thermoplastic printed parts lack mechanical strength, resulting in their limited use in practical applications. Therefore, adding reinforced materials such as carbon fiber can yield fiber reinforced plastic composite with a significant increase in strength, stiffness, and Young's modulus, while enhancing the thermal conductivity as well [6]. Some researchers focused on only one processing parameter such as raster angle [7] while [8] focused on the effects of infill density, extrusion temperature, raster angle and layer thickness on the mechanical properties of 3D printed materials.…”

Rapid innovations in 3D printing technology have allowed highly complex parts to be manufactured quickly and easily, particularly for prototyping purposes. Fused Deposition Modeling of thermoplastic materials is one of the most commonly used techniques in three-dimensional (3D) printing. The major aim of Fused Deposition Modeling (FDM) is to design and manufacture usable parts for fields such as engineering and medicine. Therefore, it is essential to investigate the mechanical properties of such FDM processed structures. One of the most commonly used materials currently on the market is Polylactic Acid (PLA). The main purpose of this paper is to investigate the effects of aging and heat treatment on the tensile properties of PLA printed test specimens. The tensile properties of parts manufactured by the 3D printer are influenced by various parameters such as extrusion temperature, infill density, building direction, layer height, etc. A total of 96 specimens were built by altering building orientation and layer height to estimate and compare the tensile properties of the printed parts. To investigate the aging effect, 30 of 96 specimens were printed 6 months before the tensile experiment. Half of both aged and new specimens were cured in an oven at 57.5 [�ŞC] for 3 hours while the other half endured no heat treatment. After the performed measurement, it can be concluded that heat treatment generally improves structural strength of the printed parts, while aging decreases it. However, these effects are highly dependent on the layer thickness and printing quality. The tensile test is conducted according to the ASTM D638 standard. The fractured samples were further characterized using an electron microscope.
