“…Conversely, as the layer height and nozzle temperature were reduced, the flexural stress value tended to decrease, exhibiting a trend similar to that observed for tensile strength. The results of this study are consistent with those of other studies that have demonstrated a similar trend with regard to the impact of printing parameters on the flexural properties [46,78,79]. A comparison of the flexural properties of the vPLA:PC-PLA (50:50) blended specimens with 100% recycled PLA and 100% vPLA showed a clear increase in flexural properties compared to the rPLA specimens, and a slightly lower result than the vPLA specimens under the same experimental conditions (Figure 13).…”

Sustainable manufacturing practices are becoming increasingly necessary due to the growing concerns regarding climate change and resource scarcity. Consequently, material recycling technologies have gradually become preferred over conventional processes. This study aimed to recycle waste polylactic acid (PLA) from household-disposed cups and lids to create 3D-printed parts and promote sustainable manufacturing practices. To achieve this, the current study utilised virgin and post-consumer PLA (sourced from household waste) blends. The PC-PLA wastes were shredded and sorted by size with the aid of a washing step, resulting in a filament with a 1.70 ± 0.5 mm diameter without fragmentation or dissolution. A 50:50 wt.% blend of virgin PLA (vPLA) and PC-PLA was selected as the standard recycling percentage based on previous research and resource conservation goals. The study investigated the impact of three 3D printing parameters (layer height (LH), infill density (I), and nozzle temperature (NT))on the quality of 3D-printed parts using a three-level L9 Taguchi orthogonal array. The findings revealed that blending PC-PLA with vPLA led to significant improvements in the tensile, flexural, and impact strengths by 18.40%, 8%, and 9.15%, respectively, compared to those of recycled PLA. This conclusion was supported by the investigation of the fracture surface area, which revealed fractographic features associated with printing parameters, such as plastic deformation and interfilament debonding. An ANOVA analysis revealed a positive influence of larger layer height and high nozzle temperature on the mechanical properties. Subsequently, the optimal printing parameters (LH: 0.3 mm, I: 100%, and NT: 215 °C) were determined using the S/N ratio, and a confirmation test using the optimum printing parameters exhibited a strong correlation with statistically predicted outcomes. Finally, the study used optimum printing parameters to fabricate 100% post-consumer recycled PLA 3D printed parts, demonstrating their potential for low-strength applications. Based on these findings, it can be concluded that virgin and post-consumer recycled PLA blended filament for fabricating 3D printed components is an effective way to support plastic recycling in the context of a circular economy.

“…However, this method requires specific dies and extruders. This is costly and complex, thus, it is not suitable for small-batch production [11][12][13][14][15][16]. Moreover, the prepreg in CFRTC based FFF printing is predetermined before printing, and the fiber layout and content are fixed, which cannot play a critical matrix role.…”

In order to improve the strength and surface quality of fiber-reinforced composite 3D printed parts and reduce the overfilling and underfilling caused by the manufacturing process of molten filaments under continuous paths, a co-extrusion control and optimization method based on matrix adaptive feeding with printing speed and deposition spacing is proposed in this paper. The method not only achieves surface void filling under different paths, but also reduces the porosity of the printed parts and improves the strength of the printed parts by adjusting the matrix extrusion under different deposition spacings. Compared with the common co-extruded model, the tensile strength is increased by 18% , the bending strength is increased by 23.4% and the porosity decreased by 54.4%. The proposed method is applicable to models with arbitrary continuous infill patterns and improves the quality of fiber-reinforced printed parts, especially to avoid structural failure due to uneven filling.
