Abstract

3D printer is widely used in producing and manufacturing prototypes as well as functional parts due to its ability to make three dimensional object by layering technique and also its various options of materials. It is found that mechanical properties of 3D printed part are affected by the values of the process parameters used in the 3D printing process. In this project, the process parameter of layer thickness, raster orientation and infill density are set as the manipulated variables while tensile strength of the 3D printed part is set as the responding variable. This project aims to identify the relationship between the input process parameters and the tensile strength of FDM printed part, the correlation among the input process parameters, the significance of input parameters towards the responding variable and also the optimized value of the input process parameters to maximize the tensile strength of the FDM printed part. Taguchi orthogonal array is used to determine the total number of experiment runs and combination of levels of each input process parameters that are needed to be executed. Multiple regression model analysis, analysis of variance and Taguchi signal-to-noise ratio are statistical methods that are used to identify the relationship, correlation, significance and optimum values of the input process parameters in maximizing the tensile strength of the FDM printed part. It is obtained that the tensile strength of the FDM printed part is inceasing with the increasing value of the layer thickness, raster orientation as well as infill density. There is no correlation between the input process parameters. Raster orientation is significant in maximizing the tensile strength of the FDM printed part. The optimum value of each input process parameters in maximizing the tensile strength of the FDM printed part is 0.28mm, 90° and 40%.
