Keywords:MPS method, Multiphase flow, Bubbles, DEM, Additive manufacturing

The bubble transfer from the powder bed to the melt pool in additive manufacturing is investigated by coupling the MPS method and DEM. It is found that bubble radius and laser beam shapes can significantly affect the bubble transfer.
