A printing system is disclosed, including a metal ejecting apparatus, which may include a structure defining an inner cavity to receive a metal printing material, and a nozzle orifice in connection with the inner cavity and configured to eject one or more droplets of a liquid metal may include the metal printing material. The printing system also includes a first print material feed system configured to supply a first print material into the inner cavity. The printing system also includes a second print material feed system may include a second print material configured to measure a level of metal printing material in the inner cavity, where the second print material is a wire. A method of sensing and controlling level in a metal jetting apparatus is also disclosed.
