Description

technical field [0001] The invention belongs to the technical field of electrochemical manufacturing, relates to a multi-metal electrochemical 3D printing device, and also relates to a multi-metal electrochemical 3D printing method for manufacturing metal workpieces by using the printing device. Background technique [0002] 3D printing is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. Different from the traditional processing and manufacturing mode of raw material removal, cutting, and assembly, 3D printing is a "bottom-up" manufacturing method through material accumulation, from scratch, which made it impossible in the past to be constrained by traditional manufacturing methods. The manufacture of complex structural parts realized becomes possible. At present, SLS, EBM and other methods are almost used for metal 3D printing. These methods need to consume a lot of ene...

Different from the traditional processing and manufacturing mode of raw material removal, cutting, and assembly, 3D printing is a "bottom-up" manufacturing method through material accumulation, from scratch, which made it impossible in the past to be constrained by traditional manufacturing methods. Realized manufacturing of complex structural parts becomes possible

At present, SLS, EBM and other methods are almost used for metal 3D printing. These methods need to consume a lot of energy to melt the metal, and they also face the problem of metal being oxidized at high temperature and harmful gases generated during processing. And consumables are expensive, unable to enter the consumer-grade field, and unable to print multiple metal mixtures at one time. From this point of view, traditional 3D printers limit the application of 3D printers in printing metals.

In recent years, a metal printing technology that uses electrochemical metal deposition for 3D printing has emerged in this field. However, due to the large contact area between the electrolyte solution of this electrochemical metal deposition printing technology and the printed workpiece, the current It will not be concentrated at one point, but will diffuse to a large area with the metal ion solution, so that the printing accuracy of this electrochemical 3D printing method is very low
