Abstract: An example three-dimensional (3D) printing kit includes a particulate build material, which includes from about 80 wt % to 100 wt % metal particles based on a total weight of the particulate build material. In some examples, the kit also includes a binder fluid, which includes water and a curable polyurethane adhesion promoter in an amount ranging from about 0.5 wt % to about 15 wt % based on a total weight of the binder fluid. The curable polyurethane adhesion promoter is formed from a polyisocyanate; an acrylate or methacrylate, the acrylate or methacrylate having at least one hydroxyl functional group and having an acrylate functional group or a methacrylate functional group; a carboxylic acid including one or two hydroxyl functional groups, an amount of the carboxylic acid ranging from 0 wt % to about 10 wt %; and a sulfonate or sulfonic acid having one or two hydroxyl functional groups or one or two amino functional groups.

Abstract: A three-dimensional printing kit, as presented herein, can include a particulate build material and a binder agent. The particulate build material can include from about 80 wt % to 100 wt % metal particles based on the total weight of the particulate build material. The binder agent can include an aqueous liquid vehicle, an acrylic polymer or copolymer latex dispersion, a sulfonated small-molecule dispersed pigment, and a solubilized dihydrazide. A sulfonated small-molecule of the sulfonated small-molecule dispersed pigment can be from about 100 g/mol to about 2000 g/mol. The binder agent can exclude a polymeric dispersant.
