This research focuses on investigating the dimensional deviations in the Fused Deposition Modelling process using ABS material and optimizing 3D printing parameters. The study found that small-sized features have higher dimensional deviations and identified the significant impact of infill percentage and number of shells on the dimensional deviation of 3D printed ABS samples.
The focus of this research work is to investigate the dimensional deviations obtained in the Fused Deposition Modelling process using ABS material and to perform optimization studies of 3D printing parameters. Preliminary investigations were carried out to identify the influence of size using different geometrical shapes and observed that small sized features have higher dimensional deviation. Inorder to further proceed with the optimization study, artifact with small sized geometrical features was used. Optimization studies were performed using Grey Taguchi Analysis and Taguchi Methodology considering infill percentage, layer thickness, number of shells, and speed of printing as process parameters. This study reveals that the percentage of infill material and the number of shells have a significant impact on the dimensional deviation of 33.89% and 32.43%, respectively, on 3D printed ABS samples.
