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, particularly relates to a suction combined type electrochemical micro-additive preparation method and device, and provides a suction combined type electrochemical micro-additive device. The suction combined type electrochemical micro-additive device comprises a sealed electrolytic tank, a liquid storage tank, a base plate, anelectrochemical workstation, a spray head, an electrode, an infusion pump and a three-dimensional displacement table. The electrochemical micro-additive preparation method is provided on the basis ofthe micro-additive device, and the problems that in the meniscus electrochemical micro-additive manufacturing technology, when a syringe needle moves, the meniscus stability is poor, and liquid overflowing and liquid leakage are likely to happen are solved by introducing the mode of the suction combined type spray head, and therefore, the stability of the meniscus and the printing fluency are improved; and meanwhile, the technology increases the ion flow rate in the meniscus, supplements ions consumed in the printing process, and enables a printed finished product to have a uniform surface, aclear edge and relatively low roughness, thereby improving the printing morphology.

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...
