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, initiating polymerization, 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, the first resin polymerizable group comprising a carbon-carbon double bond directly attached to an electron withdrawing group, a thermal radical initiator dispersed or dissolved in the resin component, and a retardant dispersed or dissolved in the resin component. |
