Warping deformation poses a significant challenge in the material extrusion process of ABS additive manufacturing, impacting dimensional accuracy and part quality. In this study, we aimed to optimize the printing factors to minimize warping deformation and enhance the overall performance of ABS-printed parts. The studied parameters included bed temperature, printing speed, chamber temperature, and printing temperature. To overcome the limitations of time-consuming and costly laboratory experiments, a simulation-based approach using numerical techniques and the Digimat-AM software's finite element model was employed to visualize and analyze warping deformation. The Taguchi technique was utilized to design a series of experiments, yielding valuable data for statistical analysis and optimization. The results highlighted the significant influence of bed temperature on warping deformation, followed by chamber temperature, printing temperature, and printing speed. Through systematic analysis, the "optimal" parameter settings were determined. These findings offer valuable insights for process optimization, enabling improved dimensional accuracy and reduced warping deformation in ABS additive manufacturing. By combining numerical simulation and the Taguchi method, this investigation gives a practical and efficient method for enhancing the performance of material extrusion processes, ensuring high-quality printed parts in the field of additive manufacturing.

A significant increase in 3D printing technology has been done primarily in the twenty-first century, where there are many research works going on in different fields, such as aerospace, automotive, and medical sectors to improve the 3D printing technology. This paper investigates the effect of printing with four different methods on the tensile strength of the Fused Deposition Modeling printed Polylactic Acid parts. Experimental and statistical analysis found that there is no effect in horizontal printing in both ways, but there is a significant difference in other printing methods. [ABSTRACT FROM AUTHOR]
