100 Decoding laser-metal interaction using open-source powder bed fusion to create engineered microstructures
Laser Powder Bed Fusion (PBF-LB) provides an unprecedented opportunity to study and control the coupling between laser parameters, melt pool dynamics, and microstructural evolution. The extreme thermal gradients and rapid solidification conditions intrinsic to LPBF lead to complex, non-equilibrium microstructures that can now be systematically decoded through open-source systems. By leveraging an open-architecture PBF-LB platform with full control over scan strategies, power modulation, and in-situ thermal management, it becomes possible to directly observe and manipulate the mechanisms governing grain morphology, texture formation, and phase distribution. This understanding allows for deliberate engineering of site-specific microstructures and property gradients within a single component, bridging the gap between process science and microstructure design.
