Abstract
The present disclosure is drawn to food contact compliant three-dimensional printing kits, materials, compositions, systems, and methods. In some examples, described herein is an example of a multi-fluid kit for three-dimensional printing comprising: a food contact compliant fusing agent comprising: at least about 70 wt % water based on the total weight of the food contact compliant fusing agent, food contact compliant carbon black dispersion in an amount of from about 3 wt % to about 10 wt % based on the total weight of the food contact compliant fusing agent, and at least one food contact compliant water soluble first co-solvent present in the food contact compliant fusing agent in an amount of from about 1 wt % to about 25 wt % based on the total weight of the food contact compliant fusing agent.
