1. A photocurable polymer-bonded explosive made by a method comprising:
preparing a formulation comprising:
a polymer, wherein a chemical protecting group is added to the polymer to prevent curing in the presence of one or more isocyanates except when exposed to visible light;
one or more fillers; and
one or more additives;
printing the formulation additively on a surface;
exposing each layer of the printed formulation to light in an amount that partially cures the polymer; and
exposing the printed formulation to heat in an amount that substantially cures the polymer.
