Abstract
AbstractIn this present scenario 3D printing technology is playing vital role in medical based manufacturing industries. The antibacterial Poly-Lactic Acid (PLA) blended with 2%wt. carbon nano particles were used this study. These blended materials were developed by using fused deposition modelling (FDM) 3D printing process. This fabrication process was controlled by infill rate, layer thickness, and nozzle speed. 9 different types of specimens were developed by using these predefined process parameters this will be used to make L9 orthogonal array for finding the influenced process parameter. The developed specimens are subjected to the mechanical property analysis such as tensile, flexural, compressive and hardness. The influenced process parameter also analysis through design of experiment (DoE) method. The regression analysis was employed to check optimum predefined control parameters which is more influencing in production. Furthermore, the best process parameter for mechanical properties of the developed specimens also obtained through analysis of variance (ANOVA) method.KeywordsPoly-lactic acidFused deposition modellingMechanical propertiesDesign of experimentANOVA
