Partitioning of laser energy during directed energy deposition

Additive Manufacturing, 2017
Abstract An energy balance that describes the transfer of energy is proposed for the laser-based directed energy deposition process. The partitioning of laser energy was experimentally measured and accurately validated using a special process calorimeter for Ti-6Al-4V and Inconel 625™ alloys. The total energy provided by the laser was partitioned as:

Deposition Height Prediction in Directed Energy Deposition

Metallurgical and Materials Transactions B
Abstract Using 316L stainless steel as a model material, reduced-order models are developed to predict capture efficiency, deposition height, and site-specific hardness in directed energy deposition. Capture efficiency is predicted over a 15 to 55 pct range using a dimensionless number derived from processing ...
