Abstract: The present disclosure describes materials, methods, and systems for three-dimensional printing. In one example, a three-dimensional printing kit can include a fusing agent and a microbe-inhibiting agent. The fusing agent can include water and an electromagnetic radiation absorber. The electromagnetic radiation absorber can absorb radiation and convert the radiation energy to heat. The microbe-inhibiting agent can include a liquid vehicle and a metal bis(dithiolene) complex. The disclosure also describes methods of three-dimensional printing that utilize a metal-containing microbe-inhibiting material, which can be a metal bis(dithiolene) complex or other materials.

Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a model generator that includes a processor and memory. The model generator obtains an input that indicates a property of a conductive element to be printed and obtains a template which defines a lattice structure for the conductive element. The model generator also generates a latticed conductive element model based on the template and the input. The system also includes a three-dimensional printing controller to trigger selective hardening of build material to form the latticed conductive element.
