During additive manufacturing, where the magnesium alloy is being deposited in a layer-by-layer manner, solidification of the melted portion of a deposited layer is performed in such a way as to ensure that about 15 percent or more of the portion being solidified includes a non-equilibrium eutectic constituent.
