PBF_CM247LC_multitrack.mp4 - Video of simulation showing 6 tracks of PBF-LB/M of CM247LC on a 100μm powder bed; bidirectional scanning path; substrate coloured light grey, powder coloured dark grey, meltpool coloured by temperature.

PBF_CM247LC_validation.png - Image showing comparison of cross-sectional weld bead obtained experimentally and in simulation for a single track of CM247LC scanned on 100μm powder bed.

PBF_IN713LC_balling.mp4 - Video of simulation of PBF-LB/M of IN713LC where insufficient heat input (452W) leads to surface energy-driven defect called balling; accompanying image of experimental result on the right

PBF_IN713LC_Q5plus.png - Image of simulation and experimental result of PBF-LB/M of IN713LC with sufficient heat input to prevent balling (520W).

PBF_IN713LC_validation.png - Image showing comparison of cross-sectional weld bead obtained experimentally and in simulation for a single track of IN713LC scanned on 50μm powder bed.
