Abstract
Fused Deposition Modeling (FDM) is an additive manufacturing technology which is used to print the 3D (Three-Dimensional) object. It has relatively low surface qualities that will affect the performance of the printed part. Thus, this research has been done to analyze the selected parameter effect on the quality surface finish of the 3D printing objects and find the optimum response of processing parameters using Response Surface Methodology (RSM). In order to predict the surface roughness, three parameters have been chosen which are layer thickness, print speed and fill density. The relations among responses and process parameters are determined and their validity is proved using Analysis of Variance (ANOVA). Then, the response surface plots are analyzed to establish main factor effects and their interaction on responses. The confirmation experiment has been carried out with the response optimizer to get the optimum parameter of the surface finish quality. Based on the results obtained, the surface roughness is mainly affected by the layer thickness compared to the fill density and print speed.
