1. A method of additively manufacturing a three-dimensional object, the method comprising:
determining, with a computing device, an irradiation sequence for selectively consolidating a powder material using an energy beam system of an additive manufacturing machine; and
providing control commands from the computing device to the energy beam system, the control commands configured to cause the energy beam system to emit a plurality of energy beams to selectively consolidate the powder material;
wherein the irradiation sequence is based at least in part on a predicted location of one or more fume plumes emitted from the powder material when irradiated by the plurality of energy beams, and wherein the predicted location of the one or more fume plumes is based at least in part on a fume plume model.
