In his dissertation, Arvind Chouhan investigated the critical interfaces in multi-material Laser Powder Bed Fusion. This advanced 3D printing technique combines different metals in a single component, but defects like cracks and pores often form where the materials join, compromising quality.
The research scientist of the department Process Engineering developed novel numerical models (DEM, CFD and Phase-Field) and combined them with experiments to understand the complex physics of the fusion process. His work reveals the mechanisms behind defect formation and offers strategies to ensure a strong, reliable bond.
His research is a valuable contribution to improving the performance of additively manufactured components for demanding applications.
