ABSTRACT
In this present work a modest attempt has been made to analyze the quality of the 3D printed components made by fused deposition modeling process. A universal coupling and the impeller is taken for this study. The three different types of non-destructive testing techniques were used in this study. The techniques used in this study are eddy current test, dye penetrating test and ultrasonic test. The main objective of this study is to find the effect of layer by layer printing procedure over the quality of the printed part in 3D printing process. The results of this study shows that no significant defects were found over the quality of the 3D printed parts and the surface is observed good in all the directions without any significant variation. The density of the minute porosity percentage variation is observed significantly in the lateral direction opposite to the printing orientation.
