1. A three-dimensional printing kit, comprising:
a build material powder including from about 80 wt % to 100 wt % of polymeric particles having a D50 particle size from about 10 μm to about 150 μm, wherein the polymeric particles are selected from the group consisting of polyacetal particles, polyacrylate particles, polybutylene terephthalate particles, polycarbonate particles, polyester particles, polyether ketone particles, polyethylene terephthalate particles, polyethylene particles, polypropylene particles, polystyrene particles, polyurethane particles, thermoplastic polyamides particles, thermoplastic polyurethane particles, copolymer particles thereof, and a mixture thereof; and
a fusing agent contained separately from the build material powder and including an aqueous liquid vehicle and a natural food-derived fusing compound dispersed in the aqueous liquid vehicle, wherein the natural food-derived fusing compound is in the form of dispersed particles having a D50 particle size ranging from about 10 nm to about 5 μm and has an absorption peak from about 340 nm to about 780 nm.
