EXPERIMENTAL INVESTIGATION ON SPECIMENS MAKINGAND ANALYSIS OF THE MECHANICAL PROPERTIES OFTHE ANTIBACTERIAL PLA PREPARED BY USING THEFUSED DEPOSITION MODELING PROCESS

Abstract

Abstract: In this experimental investigation, the tensile, flexural and compression specimens of antibacterial PLA materialswere printed by the help of the fused deposition modeling process. The different factors in the process were taken as printspeed, in-fill density and layer height. The experiment was organized by selecting the said factors at the three levels usingTaguchi L9 method for estimation of the ideal state for the successful printing of the desired number of specimens. Themaximum tensile, compressive and flexural strength is obtained as 25.08MPa, 57.29MPa and 36MPa respectively. Theuseful factors for the printing of the said specimens are print speed, 80mm/sec then infill density, 80% and layer height,120microns. The experimental outcomes are useful to decide the suitable factors and their working levels for the printing ofthe specimens and parts for the appropriate use and applications.Keywords: Anti-bacterial PLA; Larger is better; Fused deposition modeling (FDM); Tensile strength; Compressive strength;Flexural strength
