“…The optimal results were obtained using an integrated approach of desirability and WASPAS, providing a guideline for fabricating assistive devices with highdimensional accuracy. Kumar et al [20] conducted an experimental investigation of the influence of FDM parameters (raster width, infill density, and raster angle) on the mechanical characteristics of PLA parts under compressive and flexural loading, observing the considerable impact of infill density on compressive strength and modulus. Begum et al [21] developed a novel structure for evaluating flexible porosity in bone scaffolds made of polyamide (PA 2200).…”

The impact of infill parameters on compressive strength and the dimensional accuracy deviation of PLA was investigated • Infill density had the most impact on strength, while layer thickness had the greatest impact on dimensional accuracy. • The model fits the data well, with a max of 0.44% and 0.948% error for strength and average deviation, respectively.Fused deposition modeling (FDM) is an additive manufacturing (AM) technique frequently used to create prototypes and parts with intricate geometrical designs.It is gaining popularity since it enhances products by removing the need for expensive equipment. The materials used, the printing process, and the parameters influence the mechanical properties of printed objects. The quality and functionality of the parts are impacted by FDM process parameters. This study focused on the impact of six parameters on the mechanical and physical properties of samples printed using the FDM machine (Creality Ender-5 Pro). The infill density percentage, infill pattern, layer thickness, shell thickness, number of top/bottom layers, and the percentage of infill overlap have been taken as the process parameters. The compressive strength has been calculated using the ASTM D695 compression test. The results illustrated how printing parameters affected samples' mechanical and physical properties, which were proven by the ultimate compression stress UCS and the percentage of compression average deviation. The analysis of variance shows the significance of infill density (100%) for UCS, while layer thickness (0.15 mm) is significant for compression average percentage deviation. For instance, the increase in the infill density from 20% to 100% shows that the strength climbed from 4 MPa to 56.5 MPa. Similarly, reducing layer thickness from 0.3 mm to 0.15 mm results in a diminished dimensional accuracy deviation from 1.65% to 0.446%, approximately three times less than that of the specimen with a 0.3 mm layer thickness.

The purpose of this study is to examine the mechanical properties of components produced through the Response Surface Methodology for polylactic acid, utilizing the Fused Deposition Modeling 3D printing technique. Polylactic acid is a commonly employed biodegradable polymer, making it a desirable substance for diverse applications. This study involves carrying out experiments to vary process printing parameters like layer height or thickness, part orientation, and infill density. The values of these parameters were obtained using a Response Surface Methodology Box–Behnken experimental design. The mechanical performance of the 3D Printed polylactic acid fabricated was assessed by evaluating their flexural and tensile strength. The test samples for measuring tensile and flexural strength are fabricated according to American Society for Testing and Material standards. The findings suggest that higher strength is achieved when using increased layer height and infill levels. The experimental results indicated that specimens with a filling ratio of 80% exhibited greater tensile strength, while the flexural strength of samples with 50% infill was observed to be higher. Regression analyses and multi-optimization techniques were employed to predict the experimental results. This study provides valuable insights that can significantly impact various industries. Our research on the complex interactions between process variables and mechanical properties has major implications for improving high-strength component manufacturing. As demand for dependable and efficient 3D-printed materials rises, our discoveries improve material design and manufacturing methods, making a significant contribution to the field.
