Abstract

Methods of additively manufacturing a three-dimensional object include irradiating a first build plane region using a first energy beam defining a beam diameter, the first energy beam travelling along a first oscillating path in a first direction to consolidate a first wall defining a thickness perpendicular to the first direction, wherein a build material adjacent a first side of the first wall and the build material adjacent a second side of the first wall, opposite the first side of the first wall, remains unconsolidated; and wherein the thickness of the first wall is greater than the beam diameter.
