Delayed cure additive manufacturing

A method for manufacturing a part having a completed shape, comprising

• fabricating, in an additive fabrication stage, an object including build material for the part in an uncured or incompletely cured form and a solid mold forming a cavity comprising the completed shape and containing the build material;
• and
• curing the part, in a curing stage that occurs after the additive fabrication stage;
• wherein, in the additive fabrication stage, material that forms the object is deposited incrementally including depositing build material for the part in a liquid phase and depositing material for the solid mold, and during the additive fabrication stage the material for the solid mold solidifies to form the solid mold, the solid mold being removable by exposing said mold to a second temperature;
• wherein the build material comprises a wax, a monomer, and a polymerization initiator and undergoes a phase change mechanism and a distinct polymerization mechanism, the phase change mechanism occurring during the additive fabrication stage and causing a phase change of the build material from a liquid to a non-liquid, the build material being curable by exposure to a first temperature lower than the second temperature;
• wherein the distinct polymerization mechanism is initiated after the additive fabrication stage by heating the object including increasing a temperature of the object to the first temperature, the heating of the build material causing initiation of the distinct polymerization mechanism without causing removal of the solid mold, occurs during the curing stage, and occurs after the additive fabrication stage of the object, and cures the build material by the distinct polymerization mechanism,
• wherein the process further comprises heating the object to the second temperature after the curing stage to remove the solid mold from the part.
