Schematic of the photopolymerization approach used produce semicrystalline, crosslinked thiol-ene materials to improve the mechanical performance of printed components. A stoichiometric amount of crosslinker was included in the original HDT-DAT formulation at concentrations low enough to maintain crystallinity. Several prints were processed post-manufacture by heating above T_m and conditioning at that temperature until the crystallites melted to form an amorphous network.
