1. A method of three-dimensional manufacturing comprising:
depositing a layer of powder in a powder bed, the layer comprising particles of at least a first component and a second component of a two-component reactive material;
dispensing a first solution containing a solvent selected to cause the two components to form one or more cross-linked regions of a three-dimensional object;
iterating the depositing and dispensing to form subsequent layers of the three-dimensional object until the object is formed; and
removing any unwanted particles from the object.
