System and method for making a structured material

1. A system for forming a bulk material having insulated boundaries from a metal material and a source of an insulating material, the system comprising:

a heating device;

a deposition device;

a coating device;

a support configured to support the bulk material; and

wherein the heating device heats the metal material to form particles having a softened or molten state and the coating device coats the metal material with the insulating material from the source and the deposition device deposits the particles of the metal material in the softened or molten state on the support to form the bulk material having the insulated boundaries; and

wherein the source of the insulating material comprises a reactive chemical source, and wherein the deposition device deposits the particles of the metal material in the softened or molten state on the support in a deposition path at a controlled rate through an orifice in response to a first pressure of the heated metal material sensed by a first sensor and a second pressure of the insulating material sensed by a second sensor such that the insulated boundaries are formed on the metal material by the coating device from a chemical reaction of the reactive chemical source in the deposition path.

2. The system of claim 1 wherein the deposition device comprises a uniform droplet spray deposition device.

3. The system of claim 1 wherein the bulk material includes domains formed from the metal material with insulating boundaries.

4. The system of claim 1 wherein the softened or molten state is at a temperature below the melting point of the metal material.
