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.
Claims15
A three-dimensional printing kit comprising:
- a binding agent including a binder in a liquid vehicle;
- and
- a particulate build material including from about 80 wt % to 100 wt % gas-atomized stainless steel particles, wherein the gas-atomized stainless steel particles include from about 3 wt % to about 15 wt % nickel and from about 10 wt % to about 20 wt % chromium and wherein an average oxygen content of the gas-atomized stainless steel particles is from about 1200 ppm to about 2200 ppm by weight.
A method of three-dimensional printing comprising:
- iteratively applying individual build material layers a particulate build material including from about 80 wt % to 100 wt % gas-atomized stainless steel particles, wherein the gas-atomized stainless steel particles include from about 3 wt % to about 15 wt % nickel and from about 10 wt % to about 20 wt % chromium and wherein an oxygen content of the gas-atomized stainless steel particles is from about 1200 ppm to about 2200 ppm by weight;
- based on a three-dimensional object model, iteratively applying a binding agent to individual build material layers to define individually patterned object layers that become adhered to one another to form a layered green body object;
- and
- sintering the layered green body object in a fusing oven to form a fused three-dimensional object.
A three-dimensional printing system comprising:
- a particulate build material including from about 80 wt % to 100 wt % gas-atomized stainless steel particles having a D50 particle size from about 5 μm to about 20 μm, wherein the gas-atomized stainless steel particles include from about 3 wt % to about 15 wt % nickel and from about 10 wt % to about 20 wt % chromium and wherein an average oxygen content of the gas-atomized stainless steel particles is from about 1200 ppm to about 2200 ppm by weight;
- and
- a fluid applicator fluidly coupled or coupleable to a binding agent including a binder and a liquid vehicle to apply the binding agent to the particulate build material to form a layered green body object.
