An additive manufactured workpiece includes one or more cavities having an inner surface. A dielectric interface is formed in the cavity, and conforms to the inner surface. The additive manufactured workpiece further includes an in-situ electrode in the cavities. The dielectric interface is interposed between the in-situ electrode and the inner surface of the workpiece. 1. An additive manufactured workpiece comprising:at least one cavity having an inner surface;a dielectric interface in the cavity and conforming to the inner surface; andan in-situ electrode in the at least one cavity,wherein the dielectric interface is interposed between the in-situ electrode and the inner surface of the workpiece.2. The additive manufactured workpiece of claim 1 , wherein the in-situ electrode comprises a graphite material.3. The additive manufactured workpiece of claim 2 , wherein the graphite material is a pressurized graphite powder.4. The additive manufactured workpiece of claim 3 , wherein dielectric interface comprises a porous film that lines the inner surface claim 3 , the porous film containing a dielectric fluid.5. The additive manufactured workpiece of claim 4 , wherein the dielectric fluid includes a fluid that contains a dielectric material is selected from a group comprising of a liquid hydrocarbon claim 4 , a silicone oil claim 4 , ethylene glycol claim 4 , propylene glycol claim 4 , polyethylene glycol claim 4 , glycerol claim 4 , and deionized water.6.
