It was found that higher tensile, flexural, and impact strengths have been observed for the samples (S4, S5, S6) having 25% infill density. The sample with 30% infill density, 245 ℃ extrusion temperature, and 25 mm/s print speed has been found to have the highest ultimate tensile strength of 35.46 MPa. The compression strength is directly proportional to the infill density. The impact strength of the samples (S3, S5, S6 and S7) was highest, where the print speed was 25 mm/s. © 2023 The Authors.

Introduction Fused Deposition Modelling (FDM) is one of the material extrusion-based additive manufacturing techniques (B Mallikarjuna et al., 2023; Mallikarjuna B, 2013; Balichakra Mallikarjuna & Reutzel, 2022). The Acrylonitrile Butadiene Styrene (ABS), Polylactic Acid (PLA), High-Density Polyethylene (HDPE) and Polyethylene Terephthalate Glycol (PETG) are common filaments used in FDM for the fabrication of various components. * Corresponding author.
