Performance Assessment of Mechanical Properties of 3D Printed ABS

Abstract

This research examines the mechanical characteristics of 3D-Printed Acrylonitrile Butadiene Styrene (ABS) produced through the Fused Deposition Modeling (FDM) technique. ABS was selected due to its widespread use, strength, durability, and ease of manufacturing. The impact of various printing parameters like Layer Height, Printing Temperature, Infill Percentage, Annealing Temperature, etc. on the Tensile strength of 3D-printed ABS samples are studied in this study. To optimize the experimental design, a Taguchi L18 orthogonal array was applied, followed by tensile tests to measure ultimate tensile strength (UTS) and strain. Statistical tools, including signal-tonoise ratio (S/N) analysis and Analysis of Variance (ANOVA), are used to determine the most influential factors. The findings reveal that layer thickness, infill density, and annealing temperature have the greatest impact on tensile strength, with the optimal settings being a gyroid infill pattern, 90% infill density, 0.16 mm layer height, and post-annealing at 120°C. The research concludes that fine-tuning these parameters can greatly improve the strength of 3D-Printed ABS parts, with the potential for further improvements through the integration of reinforcing fibers or advanced post-processing techniques.
