Abstract: A method of forming a three-dimensional object comprises the steps of forming a layer of a particulate composition, selectively depositing a liquid composition onto the layer of the particulate composition in accordance with computer data corresponding to the shape of at least a portion of a three-dimensional object, and repeating the steps a plurality of times to form a three-dimensional object. The particulate composition comprises a plurality of first particles that comprise a resin component comprising a first resin, the first resin comprising a first resin polymerizable group. Either or both of the particulate composition and the liquid composition comprise an initiator capable of initiating polymerization of at least the first resin. At least the first resin undergoes melting and polymerization in a plurality of the locations where the liquid composition has been selectively deposited.
