Abstract

This presentation summarises recent work carried out by the author’s research group over the last 15 years in modelling and experimental studies on the heat transfer, mass transfer, residual stresses, microstructure formation and component distortions in direct laser deposition for additive manufacturing of variety of materials and components. Process energy distributions and effect of process parameters on the deposition characteristics are presented. Both analytical models and finite element models will be discussed compared with experiments. The deposition strategy on component distortion will be discussed.
