Laser shape variation influence on melt pool dynamics and solidification microstructure in laser powder bed fusion

The shape variation of the laser beam is evidently observed in the laser powder bed fusion (LPBF) process because of changes in laser incidence angle and misalignment between the build plate and the laser focus plane. This issue is particularly relevant in large-scale LPBF systems where the laser be...
