This paper introduces the system components and the theory of jet electroforming for rapid prototyping, and investigates the characteristics of the technology of jet electroforming. The results show that current density and electroforming velocity increase with the increase of electroforming voltage, the practical current density can reach 380 A/dm 2 , which is much higher than the one used in traditional electroforming. The fine area of electroforming can be achieved with small size of nozzle and lower current density. Current density has great effect on the surface morphology. A group of copper parts are fabricated by the device.
