Melting modes in laser powder bed fusion
Materialia, 2019Depending on processing conditions, laser powder bed fusion (LPBF) is known to have two operational regimes - conduction mode and keyhole mode. Heat conduction is the dominant heat transfer mechanism for conduction mode, whereas heat convection is the dominant heat transfer mechanism for keyhole mode.
