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.

In an example 3D printing method, an electrical conductivity value for a resistor is identified. Based upon the identified electrical conductivity value, a predetermined amount of a conductive agent is selectively applied to at least a portion of a build material layer in order to introduce a predetermined volume percentage of a conductive material to the resistor. Based upon the identified electrical conductivity value and the predetermined volume percent of the conductive material, a predetermined amount of a resistive agent is selectively applied to the at least a portion of the build material layer in order to introduce a predetermined volume percentage of a resistive material to the resistor. The build material layer is exposed to electromagnetic radiation, whereby the at least the portion coalesces to form a layer of the resistor.
