Abstract
AbstractIn today’s world, 3D printing is a booming technology. The 3D design software CATIA® is used to design the component that will be printed in a 3D printer, and then, the 3D design file is translated to STL file format for using 3D printer software Cura. In this paper, studies mainly focus to identify the best process parameters in 3D printed models. In order to carry out different tests in 3D printed models, it is essential to choose the appropriate process parameters. Hardness test, impact test and tensile tests are to be done for finding the best parameter to achieve good mechanical properties. Hardness test is carried out using Rockwell hardness test with a numerical value ranges from 45 to 75 HRB. Charpy impact test is carried out and got the value of 3 to 11 J. Tensile strength is identified by Universal Testing Machine (UTM) with a maximum value of 7.85 kN. Then, the experimental results and process parameters are to be used to identify the best process parameters by using Taguchi and ANOVA optimization technique.Keywords3D printingPETGFDMHardnessTensile strengthImpact strengthOptimization
