Problems solved by technology

[0004] In the prior art, the meniscus-based electrochemical additive manufacturing technology has the following problems: (1) The meniscus is unstable, and it is easy to break and leak liquid, and the size of the meniscus is not easy to control, which affects the size of the meniscus. precision control
(2) The ions consumed in the meniscus cannot be replenished, and the ion concentration in the meniscus continues to decrease during the printing process, resulting in poor and uneven morphology of the printed product

Abstract

The invention belongs to the technical field of additive manufacturing, and specifically relates to a method for preparing a suction-combined electrochemical micro-additive material and a device thereof. The invention provides a suction-combined electrochemical micro-additive device, which includes a sealed electrolytic cell, a storage Liquid tanks, substrates, electrochemical workstations, nozzles, electrodes, liquid pumps, and three-dimensional translation stages. On the basis of the above-mentioned micro-additive device, an electrochemical micro-additive preparation method is proposed. By introducing a suction combined nozzle, it solves the problem that when the syringe needle moves in the meniscus electrochemical micro-additive manufacturing technology, The stability of the meniscus is poor, and the problem of liquid leakage is prone to occur, thereby improving the stability of the meniscus and the smoothness of printing; at the same time, this technology increases the flow rate of ions in the meniscus, supplementing the printing The ions consumed in the process make the printed product have a uniform surface, clear edges and less roughness, thereby improving the printing shape.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a suction-combined electrochemical micro-additive preparation method and a device thereof. Background technique [0002] Micro-sized metal parts play an irreplaceable role in communication and other fields. The current mainstream metal additive manufacturing methods have their limitations, such as low forming precision, high production cost, and certain residual stress and thermal deformation in the finished product. Electrochemical additive manufacturing technology is a new type of additive manufacturing technology that can be used to produce micro-nano-sized metal parts, mainly through electroplating (metal ions in the electrolyte are precipitated from the electrolyte through a reduction reaction and deposited on the conductive substrate. Above) for layered processing, and then complete the three-dimensional forming of micro-nano parts. Since the el...
