Zusammenfassung:	A three-dimensional printing kit can include a particulate build material, a binding agent, and a supportive coating agent. The particulate build material can include from about 80 wt % to about 100 wt % metal particles based on the total weight of the particulate build material. The binding agent can include binder particles dispersed in a binder liquid vehicle. The supportive coating agent can include ceramic particles having a negative coefficient of thermal expansion, a gelling compound, and a supportive coating liquid vehicle.
