Understanding melt pool characteristics in laser powder bed fusion: An overview of single- and multi-track melt pools for process optimization

Laser powder bed fusion (LPBF) has made significant progress in producing solid and porous metal parts with complex shapes and geometries. However, LPBF produced parts often have defects (e.g., porosity, residual stress, and incomplete melting) that hinder its large-scale industrial commercializatio... View More
