Abstract: Examples of a three-dimensional (3D) printing kit include a particulate build material and a binder fluid. The particulate build material includes from about 80 wt % to 100 wt % metal particles based on a total weight of the particulate build material. In some examples, the binder fluid includes water, polymer particles in an amount ranging from about 1 wt % to about 40 wt % based on a total weight of the binder fluid, and a blocked polyisocyanate adhesion promoter in an amount ranging from about 0.05 wt % to about 5 wt % based on the total weight of the binder fluid. In some other examples, the binder fluid includes water and the polymer particles, and the 3D printing kit further includes an adhesion promoter fluid which includes water and the blocked polyisocyanate adhesion promoter.
