Thermal and elasto-plastic simulations of dual-laser powder bed fusion and comparative study of various scan strategies

Laser powder bed fusion involves highly localized and transient heat input, resulting in steep thermal gradients and residual stresses that may lead to distortion, cracking, and non-uniform mechanical properties. Dual-laser powder bed fusion (D-LPBF) incorporates a secondary laser to locally modulate the thermal field,...
