Abstract
The present disclosure is drawn to a three-dimensional printing kit and can include a particulate build material including from about 80 wt % to about 100 wt % metal particles, and a binding agent including water, from about 0.01 wt % to about 5 wt % organic compounds, and from about 20 wt % to about 60 wt % copper nitrate.
Claims19
A three-dimensional printing kit, comprising:
- a particulate build material comprising from about 80 wt % to about 100 wt % of metal-containing particles;
- and
- a binding agent comprising:
- water;
- from about 0.01 wt % to about 8.1 wt % of organic compounds;
- and
- from about 20 wt % to about 60 wt % of copper nitrate.

A three-dimensional printing system, comprising:
- a particulate build material comprising from about 80 wt % to about 100 wt % of metal-containing particles to be applied as individual layers during a build of a green body object;
- a binding agent to be selectively applied to the individual layers during the build to form the green body object in layers within a powder bed of the particulate build material, the binding agent comprising an aqueous liquid vehicle and a copper nitrate;
- and
- a heat curing device to cure the green body object by applying a heating profile to the green body object at a temperature of from about 70° C. to about 200° C. for a time period of from about 30 minutes to about 8 hours, wherein after heat curing, from about 30 wt % to 100 wt % of the copper nitrate in the green body object is in the form of copper hydroxynitrate.
