Electrochemical metal tip 3D printer and electrochemical metal tip 3D printing method

Abstract

The invention discloses an electrochemical metal tip 3D printer. The electrochemical metal tip 3D printer comprises a 3D motion bracket and a printing substrate, wherein at least one metal wire conduit is arranged above the printing substrate, a metal wire penetrates the metal wire conduit, and the front end of the metal wire extends out of the metal wire conduit to form a metal exposed part; the rear end of the metal wire is connected with one pole of a power controller; a conductive part of the printing substrate is connected with the other pole of the power controller; a metal wire controller is wound with the metal wire and can drive the metal exposed part of the metal wire to move downwards along the metal wire conduit; the printing substrate or the metal wire is arranged on the 3D motion bracket, and relative motion between the metal wire and the printing substrate is realized. Metal ions for electrochemical deposition are directly generated from the metal exposed part at the front end of the metal wire through ionization, so that 3D printing based on electrochemical metal tip deposition is realized. The invention further discloses an electrochemical metal tip 3D printing method.

Description

technical field [0001] The invention relates to a 3D metal printer, in particular to an electrochemical metal needle tip 3D printer. The invention also relates to a 3D printing method for electrochemical metal needle points.

AI Technical Summary

Problems solved by technology

However, the contact area of ​​the solution is not easy to control. When the electrolyte touches the conductive plate, the electrolyte will wet the contact surface and spread to the area outside the dropper

Even if it is possible to design a dropper with a diameter of 0.1 mm or less, the electrolyte is not easy to control within a mm diameter area

3D printers generally require plane precision to be controlled below 50 microns, and millimeter-level precision cannot meet the requirements of industrial applications.

Another problem with this method is that the solubility of metal ions near the surface becomes less and less during the printing process, and the deposition speed is limited by the diffusion speed of metal ions in the solution, so it is difficult to increase the deposition speed

[0006] Therefore, the existing electrochemical 3D metal printing technology is difficult to meet the industrial application standards in terms of printing speed and accuracy, and cannot realize industrial application
