围绕微电极的制备和电化学微增材制造系统搭建问题，拟采用离子束或电子束等高能束对制备的粗电极进行内孔中空结构加工，使得中空直径尺寸为微米级，同时在微电极的尖端安装电解质限域材料，实现对电解质的精确控制（图所示）；利用制备的限域微电极搭建电化学微增材制造系统。

Focusing on the problems of microelectrode preparation and electrochemical micro-additive fabrication system construction, it is proposed to use high-energy beams such as ion beam or electron beam to process the hollow structure of the prepared coarse electrode in the inner hole, so that the hollow diameter size is in the micron level, and at the same time, the electrolyte-limited material is installed at the tip of the microelectrode to realize the precise control of the electrolyte (shown in Fig.); the electrochemical micro-additive fabrication system is constructed by using the prepared domain-limited microelectrode.
