Abstract
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.
