Abstract

Additive manufacturing of an object includes dispensing a plurality of successive layers of powder over a top surface of a platform, fusing an object region in each of the plurality of successive layers to form the object, and fusing a brace region in a particular layer from the plurality of layers to form a brace structure to inhibit lateral motion of the powder. The brace structure is spaced apart from the particular object region by a gap of unfused powder.
