Abstract
A three-dimensional printing kit can include a binding agent and a particulate build material. The binding agent can include a binder in an aqueous liquid vehicle. The particulate build material can include from about 80 wt % to 100 wt % metal particles that can have a D50 particle size from about 5 μm to about 200 μm. Individual metal particles can include an iron-containing core and can have an oxidation barrier formed thereon. The iron-containing core can include from about 90 wt % to 100 wt % iron. The oxidation barrier can have a stable average thickness from about 0.5% to about 10% of a D50 particle size of the metal particles.
