Abstract
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.
Claims5
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;
- and
- an in-situ electrode in the at least one cavity,
- wherein the dielectric interface comprises a porous film that lines the inner surface, the porous film containing a dielectric fluid,
- wherein the in-situ electrode is on the dielectric interface and completely fills the at least one cavity, wherein the dielectric interface is interposed between the in-situ electrode and the inner surface of the workpiece such that in-situ electrode completely covers the at least one cavity and the dielectric interface.
