“…40 To develop the 3D printed samples, the printing parameters range of layer thickness, nozzle temperature, line width and printing speed are considered based on the literature, as shown in Table 2. [41][42][43][44][45] Here, the minimum nozzle diameter 0.25 mm is considered to fabricate the sample with surface texture. Here, the two different polymers such as poly-lactic acid (PLA) and acrylonitrile butadiene styrene (ABS) are considered to fabricate the samples with diamond texture on it.…”

“…In the published literatures, researchers also analysed the influenced of other printing parameter such as infill density on the wear characteristics of printed specimen that are developed with PLA and ABS polymer. [43][44][45] After analyzing the influence of 3D printing parameters on the tribological characteristics of textured samples, the next step is to optimize these FDM printing parameters by using the multi-objective GRA technique. The multiobjective GRA technique is a simplest technique to obtain the optimal responses.…”

In this paper, the 3D-printed textured samples are fabricated using fused deposition modelling (FDM) process for two different polymers such as ABS and PLA. The primary objective of this study is to investigate the influence of printing parameters on the tribological characteristics of 3D-printed textured samples. Here, the four major FDM printing parameters such as layer thickness (LT), nozzle temperature (NT), line width (LW) and printing speed (PS) are considered for the study. Whereas, the tribological characteristics of 3D-printed textured sample such as wear rate and friction coefficient are considered as output responses. The present experimental study is carried out based on the response surface methodology to evaluate the effect of these FDM printing parameters on the tribological characteristics of textured samples. These experimental results show that the line width is the most significant printing parameter followed by layer thickness. Whereas, the printing speed is the third most significant printing parameter. Furthermore, the optimized value of printing parameters for ABS and PLA are evaluated by using grey relational analysis. For the ABS polymer, the optimal value of printing parameters as layer thickness = 0.1 mm, nozzle temperature = 230°C, line width = 0.28 mm and printing speed = 75 mm/s. Whereas, for the PLA, the optimal value of printing parameters are: layer thickness = 0.14 mm, nozzle temperature = 220°C, line width = 0.31 mm, and printing speed = 50 mm/s. In addition, However, the wear rate first decreases with the layer thickness and nozzle temperature and then increases. The wear rate linearly increases with the printing speed.

“…The findings of this study demonstrate a clear positive correlation between the nozzle temperature and infill percentage and the resulting increase in hardness, which is aligned with the results evaluated by Mani et al [87] and Maguluri et al [91] for vPLA. According to Şirin et al [92], an increase in the infill percentage results in a reduction in void formation, leading to an overall increase in hardness. Another reason is that an increase in infill percentage leads to an expansion of the cross-sectional area of the material, thereby contributing to the development of a more rigid internal structure [93].…”

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.

Acrylonitrile butadiene styrene (ABS), a petroleum-based thermoplastic, is widely used in various industry. It is important to make product costs without reducing the wear characteristics of products. For this reason, over the past 20 years, researchers have focused on improving product performance by reducing material weight. The literature has limited information about the tribological properties of the ABS polymer samples produced with fused deposition modelling. In this study, gyroid-patterned ABS samples with different infill densities (25%, 50%, and 75%) were produced and the effect on the wear properties of the samples was investigated. The main aim of the study is to show the infill density effect on wear and friction performance of the samples and find the coefficient of friction values. So, this study is one of the first studies which investigated wear and friction properties of ABS polymer produced as gyroid pattern with different infill densities. The study might also be used to have an initial information whether ABS polymer can be used in additive manufacturing systems for the joint components. As the performance indicator, diameter deviation, hardness, surface roughness, test temperature, friction coefficient, weight loss, and wearing surface results of the samples were evaluated. The results show that infill density is an important property that effect the tribological and heating characteristic of ABS samples. The friction and heat of the samples increase by increasing infill density. According to the tribological test results, the highest coefficient of friction and friction temperature were reached in the samples with 75% infill density.
