Enhancing Process Control in Metal 3D Printing

This presentation will review recent developments in understanding and controlling light-matter interaction and material response associated with laser powder bed fusion additive manufacturing.  As part of the critical assessment of the physics of the process, validated hydrodynamic finite element model simulations have proven to be extremely valuable and can be used to inform rapid solidification microstructural models.  The talk will also cover new approaches to process optimization that have emerged from our modeling efforts which can improve material properties and part performance.
