Application of Taguchi Method in Investigating the Effect of Layer Thickness and Fill Angle on FDM Parts

Abstract

This paper studies the effect of Layer Thickness and Fill Angle on tensile stress of Fused Deposition Modeling (FDM) parts for Acrylonitrile Butadiene Styrene (ABS) and Carbon Fiber Reinforced ABS (CFRABS) materials by using Taguchi Method, signal-to-noise (S/N) ratio analysis and Analysis of Variance (ANOVA). From the results, it was found that layer thickness contribute to the tensile stress performance of ABS and fill angle has significant effect on tensile stress of CFRABS. It can be concluded that the optimized parameter obtained in this study for both materials are 0.18mm layer thickness and 90° fill angle.
