Parameters developement, mechanical and microstructural characterization of a 3d printed beta Ti21S alloy

This thesis presents the development and optimization of 3D printing parameters for beta titanium alloy (Ti21S) in the context of producing high-end luxury goods, specifically in the jewelry and eyewear sectors. The objective was to identify the optimal print speed and laser power settings to achieve maximum density in the printed parts, thereby ensuring superior mechanical properties and aesthetic quality. A systematic approach was employed, where multiple combinations of print speed and power values were evaluated. The resulting printed samples underwent rigorous microstructural and mechanical testing, including tensile and hardness testing, to ascertain the material properties and validate the optimal printing parameters. The findings revealed that specific parameter combinations significantly influence the density, microstructure, and mechanical performance of the Ti21S alloy. This research contributes to the advancement of metal additive manufacturing in the luxury goods industry, providing a framework for producing high-quality, customized titanium components.
