3D printing is commonly used in the manufacturing sector, where it can create various models such as simulating human and animal anatomies. As a result, 3D printing can improve the quality of life and health. The problem faced in 3D printing is mainly the quality of the printed product. Moreover, the trials and error method also leads to the waste of materials. This study aims to analyse the compressive and shrinkage behaviours of honeycomb core produced by different 3D printing parameters via integration of Taguchi and Principal Component Analysis (PCA). The Taguchi method and PCA simultaneously solve the multiple quality characteristics that relate to the problems, especially in 3D printing. The factors studied in this research are speed, infill pattern, extruder temperature, bed temperature, layer height, fill density, and thickness. Two parameters can be observed from unaided eyes: the layer height and thickness of the honeycomb. The optimal and significant factors will be expected in this study. From the findings, it can be concluded that the optimal parameter for 3D printing is the speed at 40 mm/s, infill pattern of honeycomb, 210℃ of extruder temperature, 90℃ of bed temperature, and 0.2 mm of the layer height and fill density and 1 mm of the thickness. From this study, the Taguchi method and Principle Component Analysis effectively optimise the quality characteristics of 3D printed honeycomb. [ABSTRACT FROM AUTHOR] |
