Abstract
A method of three-dimensional manufacturing including depositing a layer of powder in a powder bed, the layer comprising particles of at least a first component of a two-component reactive material, dispensing a first solution containing at least one of a solvent and a second component of the two-component reactive material the 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. A three-dimensional manufacturing system has a powder bed to hold layers of particles, and one or more print heads positioned to dispense liquid onto the powder bed to cause the particles for form one or more cross-linked regions in layers of a solid object.
