“…Some of the void formation in FDM is inevitable due to the nature of this printing process. The voids between the layers are much bigger and differ with the airgap and layer thickness of the print, while the voids present inside the filament and matrix are much smaller and difficult to control by changing printing parameters [ 191 ]. According to many experiments, it has been identified that the gaps between the layers, which contribute to the failure of the printed part by delamination, can be reduced by minimizing the layer thickness [ 192 , 193 , 194 ].…”

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.

“…Therefore, using printed samples to determine the mechanical properties will give more realistic results. In order to evaluate the effects of the above-mentioned printing parameters on mechanical properties, most of the researchers conducted tensile and bending tests [7][8][9] where for tensile testing, ASTM D638 and ISO 527 standards were preferred [10,11].…”

Parts produced by FDM (fused deposition modelling) technique, where polymer filaments are used, are anisotropic and their properties vary depending on the printing parameters, one of which is raster angle. In this study, the effects of this parameter on the tensile and the surface roughness properties were investigated. It was determined that the ultimate tensile strength (UTS) decreased with increasing raster angle; hence, 0° raster angle where tensile loading direction is parallel to the raster yielded the highest strength. Besides ±45° raster angle resulted the most ductile behaviour with the highest fracture strains. Fracture occurred due to raster failure for 0° raster angle but for 90°raster angle, it was due to the failure of the interlayer raster bonds. In the case of ±45°, both of the failure mechanisms were effective. Surface roughness values increased up to 7 µm when measurement was perpendicular to the raster and dropped below 1 µm when it was parallel to the raster.

“…Porosity is the main reason for their decrement in strength with the addition of 10 wt.% carbon content in the ABS polymer. This phenomenon could be the reason for adding carbon fiber content up to 5 wt.% and further addition resulted in the smallest value of tensile and flexural properties [14][15][16][17].…”

Fused Filament Fabrication (FFF) is the most popular and widely used additive manufacturing process for printing polymer and composite products. Various production factors influenced the strength and stiffness of the part manufactured by 3D printing. A comprehensive experimental analysis was conducted in this study to examine the effect of FFF process parameters (infill density, pattern, and layer thickness) on mechanical properties and failure mechanism. The tensile, flexural, and impact test specimens were printed using ABS and carbon fibre reinforced ABS filaments in accordance with ASTM standards. Furthermore, dynamic properties are studied using dynamic mechanical analysis to estimate the loss factor and glass transition temperature under the impact of temperature and frequency in addition to static properties. Further, the results showed the addition of carbon fiber in ABS increases the mechanical properties. The failure modes are studied using optical microscopy and Scanning Electron Microscopy images and it has been visualized that due to improper layer deposition, poor bonding between the previous layer and low infill density creates a void in the specimen which results in poor mechanical properties. The Dynamic Mechanical Analysis showed that at higher frequency the molecular movement decreases which in turn stabilizes the composite behavior and reduces the loss factor.
