Abstract-This study focuses on the mechanical characterization and optimization of Acrylonitrile Butadiene Styrene (ABS) specimens fabricated using Fused Deposition Modeling (FDM) without the incorporation of carbon fiber reinforcement. The objective is to analyze the tensile strength, elongation at break, and Young’s modulus of nine specimens to determine the optimal conditions for maximizing mechanical performance. Tensile testing was conducted on each sample, and key mechanical parameters such as yield strength, ultimate tensile strength (UTS), and modulus of elasticity were recorded. The results highlight the consistency in mechanical performance and identify the specimen with the highest mechanical properties. Additionally, this paper delves into the entire FDM process, including material selection, slicing, printing parameters, and post-processing, providing a comprehensive understanding of how each step influences the final mechanical behavior of the ABS parts. The findings serve as a baseline for further research on reinforced composites and establish groundwork for performance prediction in unreinforced ABS parts. These insights can be particularly valuable for industries such as automotive, aerospace, and consumer electronics where polymer parts are increasingly being produced via additive manufacturing. The scope of this study also lays a foundation for future research into composite materials and the use of machine learning for automated parameter optimization in 3D printing.
