The present disclosure is drawn to food contact compliant three-dimensional printing kits, materials, compositions, systems, and methods. In one example, a multi-fluid kit of food contact compliant agents for three-dimensional printing can include a food contact compliant fusing agent and a food contact compliant detailing agent. The food contact compliant fusing agent can include from about 70 wt% to about 96 wt% water, from about 3 wt% to about 10 wt% by solids weight of a food contact compliant carbon black dispersion, and from about 1 wt% to about 25 wt% of a food contact compliant water-soluble first co-solvent. The food contact compliant detailing agent can include from about 75 wt % to about 99 wt% water and from about 0.01 wt% to about 1 wt% of a food contact compliant chelating compound.
