A Multi-phase field lattice Boltzmann method for melting, gas/liquid flow and solidification in powder bed fusion process of Ni alloy additive manufacturing is developed. Improved lattice kinetic scheme is adapted for gas/liquid free surface flow simulation. High speed calculation is achieved by MPI&OpenMP hybrid parallelization. It is confirmed that this method has high capability to simulate the powder bed fusion process in detail.
