Investigation of Mechanical Properties of PLA based 3D Printed Dental Crown
Abstract
This research aims to comprehensively investigate the mechanical properties encompassing tensile strength, compressive strength, hardness, and saliva absorption of Polylactic acid (PLA)-based three-dimensional (3D) printed dental crowns. The study provides valuable insights into the performance characteristics of PLA-based dental crowns, with a particular focus on their ability to withstand mechanical forces and absorb saliva. PLA filament derived from PLA pellets and produced using the Fused Deposition Modeling (FDM) technique with a raster angle of 45o was employed to mechanical testing. The Creality Ender-3 S1 FDM 3D Printer is utilized for the manufacture of samples. Through meticulous comparison with the mechanical properties of natural enamel teeth, the study aims to assess the suitability of PLA-based 3D printed dental crowns as a substitute for traditional dental crown materials. A detailed analysis and comparison of the study leads to a significant contribution to understand PLA-based dental crowns and their potential in dental prosthetic applications. Ultimately, the outcomes of the study advocates for the adoption of PLA-based dental crowns as a viable and effective alternative in dental practice.
