Evaluating Compressive Strength in 3D-printed Concrete Structures: A Comparative Study of ANSYS Simulations and Experimental Data

Abstract This paper investigates the use of 3D printing technology in concrete construction, with a focus on the compressive strength of 3D-printed structures. The study highlights the growing interest in 3D-printed concrete (3DPC) due to its potential for creating complex geometries, optimizing material usage, and reducing environmental impact. The research also examined various experimental studies that tested 3D-printed concrete samples, focusing on the differences in material composition and additives that affect compressive strength. The results of the simulations using ANSYS program were compared with experimental data, revealing discrepancies due to factors such as anisotropy, curing methods, and challenges in accurately modeling material behavior in simulations. While the simulation results closely aligned with experimental findings in some cases, significant variations were observed in others, highlighting the need for improved modeling techniques. Despite these challenges, the study underscores the potential of 3D printing in revolutionizing the construction industry. The findings suggest that continued advancements in both material science and simulation tools are necessary to fully realize the benefits of 3D-printed concrete in large-scale structural applications.
