1. A method of additively manufacturing, comprising:
determining a track for manufacturing a layer of a component from a multiple of powder particles of a powder blend, the track including a denuded region that has reduced particle density and isolated powder particles due to a prior melting energy beam traversing a prior track adjacent to the track;
traversing the track with a conditioning energy beam to sinter the isolated powder particles of the multiple of powder particles along the denuded region; and
traversing the track with a melting energy beam subsequent to the conditioning energy beam to form the layer of the component, whereby the layer of the component is formed without overheating the isolated powder particles, and the melting energy beam generates an adjacent denuded region having isolated powder particles; and
repeating the traversing steps along a next track along the adjacent denuded region.
