Mechanisms and elimination strategies of overhang closure failure during support-free laser powder bed fusion

Laser Powder Bed Fusion (LPBF) is a promising technique for manufacturing components with complex geometries. However, its application is limited for critical engineering parts featuring enclosed interior overhangs due to the necessity of sacrificial support structures. Thus, achieving support-free...
