Description

technical field [0001] The invention relates to the technical field of three-dimensional electrodeposition, in particular to a highly localized three-dimensional electrodeposition device and method. Background technique [0002] Electrodeposition is a metal additive manufacturing technology based on the principle of electrochemical cathodic deposition. Compared with other metal additive manufacturing technologies, such as laser additive manufacturing, electron beam additive manufacturing and arc additive manufacturing, etc., no subsequent annealing is required. And homogenizing heat treatment, no residual stress. In theory, it is only necessary to induce the metal atoms or grains formed by redox reactions to stack up controllably according to the design intention, and the electrodeposition technology can be used to process or print metal-based structures and parts of arbitrary shapes. [0003] At present, there is already a 3D printing technology for metal parts using elect...

Problems solved by technology

However, since the working fluid flows out from the nozzle and spreads unrestrictedly on the surface of the workpiece, under the action of stray current, stray deposits tend to appear in the non-deposition area of ​​the workpiece surface, so the microstructure resolution of its electrodeposition is generally 1 / 2 of the diameter of the nozzle. Ten times, the localization is poor, how to improve the localization of electrochemical deposition has become a difficult problem
