A three dimensionally integrated numerical method using lattice Boltzmann method and multi-phase field method is proposed for simulating melting and solidification of metal alloy in laser powder bed additive manufacturing process. Simulations are performed in conditions of different beam power values. Simulated solidified microstructures are confirmed to be qualitatively agreement with experimental measurements.
