1. A system for automating tool touch-off in an additive manufacturing process, the system comprising:
a substrate, comprising:
a bottom layer comprising a conductive material;
a middle layer disposed directly on the bottom layer, the middle layer comprising a binding material; and
a top layer disposed on the middle layer, the top layer comprising a non-stick conductive material,
wherein the non-stick conductive material comprises a fluoropolymer and carbon nanotubes, and
wherein print material is configured to be deposited onto the top layer; and
at least one conductive object extending through the top layer, the middle layer, and at least partially into the bottom layer, the at least one conductive object providing an electrical connection between the bottom layer and the top layer; and
a circuit comprising the substrate and a nozzle of an additive manufacturing device,
wherein the circuit is configured to close when the nozzle contacts the top layer of the substrate and the electrical connection is created between the top layer and the bottom layer by current passing from the top layer, through the at least one conductive object and to the bottom layer.
