| Abstract Scope |
Spatter deposition has been found to have serious effects on mechanical properties of the metal parts printed using laser powder bed fusion technique. The spatter powder formation can cause unfavorable changes in phases and impurity content and may result in the formation of defects in the as-fabricated parts. This study is the first of its kind focusing on mitigation of spatter formation through a novel technique of spraying nonflammable welding liquid during the LPBF process. Identifying the spatter particle size distribution and dampening its formation have been the focus of this study. Characterization of the powder spatter behaviors for Ti-6Al-4V have been made through image processing, microstructure characterization, and compositional analysis. The findings of this study will help in improving the mechanical properties and reducing the post-processing procedures required for the parts processed by LPBF. This study is believed to bring a new perspective in production planning and print quality optimization to obtain an enhanced performance from laser powder bed fusion technique. |
