Application of Taguchi methodology in evaluating the IZOD impact strength of FDM 3D printed component

Abstract

An additive manufacturing technique called fused deposition modelling (FDM) produces solid items layer by layer by melting filaments. The IZOD impact strength of the FDM 3D printed parts was determined using IZOD impact testing equipment following the ASTM D 256 standard. Based on the IZOD impact strength of FDM 3D printed ABS parts, the current study seeks to determine the optimized 3D printing configuration. Taguchi methodology-based optimization technique was used to identify the optimum printing configuration. The L9 orthogonal array was designed with three-factor at three different levels. According to the ISO 3534–3, five test specimens of each configuration were printed and impacted in the IZOD impact testing equipment. The highest value of IZOD impact strength is determined by these optimized 3D printing settings for FDM 3D printed ABS material.
