Three-dimensional electrodeposition systems and methods of manufacturing using such systems

A method of forming a three-dimensional structure, comprising:

• providing an electrolytic bath in a receptacle, the electrolytic bath comprising a metal salt;
• disposing a counter electrode at least partially within the electrolytic bath;
• coupling the counter electrode to a working electrode;
• and
• flowing the metal salt through a nozzle coupled to the receptacle to deposit, on a surface of the working electrode, a metal of the metal salt.

An electrodeposition system for additive manufacturing of a three-dimensional nuclear fuel element, the electrodeposition system comprising:

• a plurality of electrochemical cells, each electrochemical cell of the plurality comprising:
• a receptacle comprising an electrolytic bath;
• at least one nozzle opening from the receptacle towards a working electrode of the electrochemical cell;
• and
• a counter electrode extending into the electrolytic bath,
• each electrolytic bath of the system comprising a different composition of nuclear fuel material salt dissolved in ionic liquid at a temperature of less than about 80° C.;
• and
• the working electrode extending below the at least one nozzle of all of the plurality of electrochemical cells.
