Methods, systems, and apparatus, for hybrid additive manufacturing of parts. In one aspect, a method includes providing a workpiece and manufacturing multiple additive layers on a surface of the workpiece. Manufacturing each of the multiple additive layers includes forming one or more formed layers on a surface of the workpiece by depositing a quantity of powder material on a growth surface, the growth surface inclusive of at least one of a first surface of the workpiece and a second surface of a previously formed layer, and applying a first amount of energy to the quantity of powder material to fuse the particles of the powder material into a formed layer fused to the growth surface, where the formed layer includes a formed surface, and further applying a secondary process to a particular area of the formed surface of the one or more formed layers on the workpiece.
