A new type of layered manufacturing technology that combines the jet electrodeposition method and arapid prototyping concept is presented. The manufacturing method adopts multilayerscanning electrodeposition using an electrolyte jet to fabricate a micro-metallic part with ananocrystalline microstructure, which simplifies three-dimensional processing. The research resultsshowed that key parameters, including the current density, applied voltage, nozzle diameter and jet speed,impacted the forming process and deposition quality. The effective current density was observed to reach350 A/dm2, at which point nanocrystalline grains with sizes from 30-50 nm were obtained. It was foundthat the application of an optimized applied voltage, nozzle diameter, current density and jet velocityincreased the forming speed and improved the mechanical performance of the finished parts. A group ofnanocrystalline copper parts with a good shape and mechanical properties was produced using optimizedparameters with the jet electrodeposition method..
