A three-dimensional printing kit can include a binding agent and a particulate build material. The binding agent can include a binder in a liquid vehicle. The particulate build material can include from about 80 wt % to 100 wt % gas-atomized stainless steel particles. The gas-atomized stainless steel particles can include from about 3 wt % to about 15 wt % nickel and from about 10 wt % to about 20 wt % chromium and can have an average oxygen content of from about 1200 ppm to about 2200 ppm by weight.

Three-dimensional printing with gas-atomized stainless steel particles

A three-dimensional printing system can include a particulate build material including metal particles. The three-dimensional printing system can include a binding agent applicator fluidly coupled or coupleable to a binding agent. The three-dimensional printing system can include a suppression agent applicator fluidly coupled or coupleable to a melting point suppression agent, the melting point suppression agent including a dispersion of melting point suppression particles. The three-dimensional printing system can include a hardware controller to generate a command to direct the binding agent applicator to iteratively apply the binding agent to the particulate build material to form individually patterned object layers of a green body object, and direct the suppression agent applicator to iteratively apply the melting point suppression agent to a discrete location of the individually patterned object layers. The discrete location can include a discrete surface region of the green body object.
