Vinyl sulfonyl agents for thiol-ene polymerization and related uses

A method for manufacturing a part includes fabricating an object in an additive fabrication stage, the object including a solid mold forming a cavity in the shape of a part with uncured or incompletely cured build material disposed therein. The build material in the cavity is cured in a curing stage that occurs at least partially after the additive fabrication stage. The build material undergoes a phase change mechanism occurring during the additive fabrication stage and a distinct polymerization mechanism occurring during the curing stage and at least partly after the additive fabrication stage of the object and cures the build material by a polymerization process.
