1. A three-dimensional printing kit comprising:
a powder bed material comprising polymer particles and phosphorescent pigment particles mixed with the polymer particles,
wherein the phosphorescent pigment particles are selected from the group consisting of calcium sulfide, calcium strontium sulfide, calcium strontium sulfide doped with bismuth, calcium aluminate, calcium aluminate doped with europium, strontium calcium aluminate, zinc sulfide doped with copper, zinc cadmium sulfide, zinc cadmium sulfide doped with copper, strontium aluminate, strontium aluminate doped with europium and dysprosium, barium aluminate, barium aluminate doped with europium, and a combination thereof; and
a low-tint fusing agent comprising water and an electromagnetic radiation absorber wherein the electromagnetic radiation absorber absorbs radiation energy and converts the absorbed radiation energy to heat.
