Material-structure-performance integrated laser-metal additive manufacturing (2021, positive): “Essentially, residual stresses during laser AM can be reduced by weakening local thermal gradients in the melt pool, which can be accomplished by (i) preheating the substrate and previously deposited layers (9, 17, 162), (ii) optimizing laser printing parameters to maintain constant melt pool morpho”
