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.

Abstract: A method of additive manufacturing to form a component comprises successively depositing a plurality of layers to form the component. Depositing at least one of the plurality of layers includes depositing a layer of a first particulate precursor over a platen, depositing a second particulate precursor on portions of the platen over the layer of the first particulate precursor specified by a controller, and directing energy to the second particulate precursor deposited on the portion of the platen to cause an exothermic chemical reaction between the first particulate precursor and the second particulate precursor. The exothermic chemical reaction produces heat that sinters products of the chemical reaction to fabricate the layer of the component.
