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.
