Abstract
A method of controlling an additive manufacturing process in which one or more energy beams are used to selectively fuse a powder to form a workpiece, in the presence of one or more plumes generated by interaction of the one or more energy beams with the powder. The method includes controlling at least one of: a trajectory of the one or more plumes, and the one or more energy beams, so as to prevent the one or more energy beams from intersecting the one or more plumes.
