1. An ink, comprising
a nonradiation-curable pre-polymer having at least one molecule that comprises two nonradiation-curable components and a radiation-curable component;
a polymer having at least one reactive hydrogen component; and
a photoinitiator,
wherein a concentration of the nonradiation-curable pre-polymer having at least two nonradiation-curable components is in a range of greater than 0 weight % to less than 99 weight % of a total weight of the ink.
