1. A 3-dimensional printing material set, comprising:
a particulate build material comprising thermoplastic polymer particles;
an inkjet dopant composition consisting of:
a liquid carrier consisting of:
from about 73 wt % to about 76 wt % of water;
a co-solvent; and
optionally a surfactant; and
a dopant dispersed or dissolved in the liquid carrier, wherein the dopant is present in an amount ranging from about 0.1 wt % to about 5 wt % and consists of particles that are selected from at least one of photoluminescent particles, dielectric particles, magnetic particles, ceramic particles, semi-conductor particles, electrically-conducting particles, and polymer nanoparticles; and
an inkjet fusing composition consisting of a liquid vehicle water and a fusing agent capable of absorbing electromagnetic radiation to produce heat, wherein;
the fusing agent is selected from the group consisting of carbon black, near-infrared absorbing pigments, tungsten bronzes, molybdenum bronzes, metal nanoparticles, and combinations thereof; and
the liquid vehicle consists of water.
