“…However, humping is not exclusive to the high-energy-intensity keyhole printing mode but is also observed for conduction-mode welding with lower energy intensity and shallow melt pools. Gullipalli et al, 2023 have even recently shown that reducing heat input in DED (i.e., moving from keyhole to conduction mode printing conditions) can aid in activating humping [15]. These contradictory recommendations and explanations arise from the complex non-linear interaction of physics in metal welding and printing.…”
