Abstract
The present disclosure is drawn to a three-dimensional printing system can include a powder bed material, including from 80 wt % to 100 wt % metal particles having a D50 particle size distribution value ranging from 5 μm to 75 μm and a powder bed support substrate for receiving the powder bed material. The system can also include a fluid ejector operable to digitally deposit a thermally sensitive binder fluid onto a selected portion of the powder bed material on the powder bed support substrate. The thermally sensitive binder fluid can include water, a reducible metal compound, and a thermally activated reducing agent. A light source can also be present to generate a pulse energy sufficient to cause the thermally activated reducing agent to reduce the reducible metal compound and bind metal particles together to form a green three-dimensional part.
