Additive manufacturing methods and systems

A method of additively manufacturing a three-dimensional object by one or more energy beams, the method comprising:

• consolidating a first build plane region across a powder bed using a first energy beam directed along a plurality of first hatching paths and a first contour path that defines a first outer contour portion at least partially defining a first edge portion of an outer edge of the three-dimensional object, wherein the first edge portion is non-linear;
• and
• consolidating a second build plane region across the powder bed using a second energy beam selectively directed across the powder bed along a plurality of second hatching paths and a second contour path that at least partially defines a second outer edge portion at the second edge portion of the three-dimensional object, wherein the second edge portion extends into the plurality of second hatching paths along a non-linear stitching path,
• wherein an alignment of the first energy beam with the second energy beam is adjusted to control a material property of the three-dimensional object.
