“…The findings presented in this study showed the comparatively poorer mechanical properties exhibited by the specimens printed using rPLA in comparison to those printed using vPLA. In previous investigations employing rPLA, a comparable finding was documented related to a decreasing trend in flexural characteristics [3,17,22]. The observed phenomenon can be attributed to the reduced mechanical properties of recycled PLA due to its lower molecular weight [96].…”

“…In addition, the findings indicated that the samples exhibited higher tensile properties as the layer thickness and temperature increased. In previous studies utilising recycled polylactic acid, the same observation of a declining pattern in the tensile properties was noted [3,15,17,22,94].…”

“…According to existing research, the overall mechanical performance of printed specimens can be improved through the modification of various printing parameters, such as nozzle/extrusion temperature, layer thickness/ height, nozzle diameter, infill percentage, infill pattern, printing speed, build orientation (flat, edge and upright), raster/ infill orientation, top and bottom layer thickness etc. [3,17,22]. Therefore, it is essential to optimise and control all of these factors effectively within FDM manufacturing process to fabricate components with higher dimensional precision and enhanced mechanical functionality [23].…”

“…Correia et al [25] determined that by utilising the optimal combination printing parameters, such as 0.2 mm layer thickness, 100% infill, and 40 mm/s travel speed would effectively improve the mechanical properties of rPLA. In their study, Tan et al [22] determined that optimal printing parameters for enhancing the tensile strength and flexural strength of recycled polylactic acid (rPLA) include a fan cooling speed of 100%, an extruder temperature of 190 °C, and a bed temperature of 50 °C. Breški et al [26] assessed that 30% infill and 0.1 mm layer thickness were most favourable for higher mechanical properties of rPLA.…”

The main goal of this research was to investigate the influence of additive manufacturing (AM) printing parameters on the mechanical properties and surface roughness of specimens fabricated using recycled polylactic acid (rPLA). In order to achieve this goal, significant printing parameters such as layer thickness, infill density, and nozzle temperature were selected based on prior research. A three-level L9 orthogonal array based on the Taguchi method was used in the experimental design. The mechanical properties of virgin PLA and recycled PLA printed specimens were examined and compared. To facilitate the analysis of variance (ANOVA) examination, the response data for mechanical and surface roughness parameters were transformed to signal-to-noise (S/N) ratios. The inspected responses under consideration were surface roughness, shore D hardness, tensile strength, flexural strength, and impact strength. The main findings suggested that careful consideration of the layer height was crucial for achieving optimum mechanical properties in recycled PLA specimens. Furthermore, the nozzle temperature also played an important factor that affected the mechanical and surface roughness properties of the 3D printed PLA specimens. Microscopic investigation demonstrated that the number and size of voids increased significantly when the layer thickness and temperature were low, namely 0.1 mm and 195 ℃, respectively. Finally, the optimal combination of printing parameters for each performance characteristic was determined. Following this, a confirmation test was performed using the preferred combination of parameters, which indicated a strong correlation with the outcomes predicted statistically. The results obtained from this study revealed that recycled PLA exhibited mechanical properties comparable to that of virgin PLA under certain conditions. In summary, the results of this study will serve as a valuable dataset in the field of additive manufacturing, providing valuable insights for other researchers working with recycled PLA material.

Although extensive research has been carried out on the effects of temperature on the properties of parts by fused filament fabrication, no study considered the opportunity to use different temperatures and cooling strategies for the contour and the infill region. The purpose of this investigation is to explore such an opportunity through an experimental campaign on polylactic acid. Specifically, the variations in tensile properties and warping occurring with different infill temperatures and cooling methods are documented. The results demonstrate that diversifying process parameters used for the contour and infill of the part allow for significant improvements in mechanical properties without affecting the distortion of the manufactured samples. This result can be achieved by either increasing the nozzle temperature or switching off the cooling fan during infilling.
