1. A method of additively printing an extension segment on a workpiece, the method comprising:
pretreating a workpiece-interface of a workpiece using an energy beam emitted from an energy beam source of an additive manufacturing machine, providing a pretreated workpiece-interface having received a pretreatment, the pretreatment remediating an aberrant feature of the workpiece and/or the workpiece-interface; and
additively printing an extension segment on the pretreated workpiece-interface using an energy beam emitted from the energy beam source of the additive manufacturing machine;
wherein the aberrant feature comprises one or more aberrant regions of the workpiece-interface having been determined from a digital representation of the workpiece-interface captured by a vision system;
wherein the pretreatment comprises additive-leveling a first portion of the workpiece-interface comprising a first aberrant region and melt-leveling a second portion of the workpiece-interface comprising a second aberrant region;
wherein the pretreatment comprises heat-conditioning at least a portion of the workpiece-interface comprising the one or more aberrant regions of the workpiece-interface by modifying a grain structure of the workpiece at or near the workpiece-interface; and
wherein the additive-leveling and the heat-conditioning pretreatments are performed concurrently.
