Lattice distributing type anode platform columns obtained by electroreduction metal deposition

Abstract

The invention relates to an anode assembly of a digital control electrochemical deposition fast-forming device. The anode assembly comprises an insoluble anode. The anode assembly is characterized in that a horizontal anode platform surface in a lattice distributing shape in x-axis and y-axis directions is arranged, each lattice position is fixedly provided with an anode, the lattice positions are mutually insulated to form lattice distributing type anode platform columns, and the anodes are all connected in parallel with electrochemical power supplies of the anodes; the anode platform columns are internally provided with lattice distributing anode liquid delivery channels; and an expanding containing cavity is arranged at the periphery of each anode end surface positioned on the anode platform surface, and the expanding containing cavities and the openings of the anode liquid delivery channels are mutually communicated. The anode assembly disclosed by the invention has the greatest advantage that all electrode points can simultaneously work, that is to say, parallel printing is achieved, thereby being especially high in working efficiency and less in energy consumption; and in addition, the anode assembly disclosed by the invention can solve the problem that electric field intermittence is correspondingly generated inevitably on spaced insulating parts positioned among electrodes because the electrodes positioned on the anode platform surface in the distributing shape need to be insulated by being spaced through insulating resin through the arrangement of the expanding containing cavities and the like, and enables the metal electroreduction deposition to be continuously and stably carried out by providing a buffer area for a metal ion solution.

Description

technical field [0001] The invention relates to a dedicated anode assembly in a numerically controlled electrochemical deposition rapid prototyping device. Background technique [0002] The equipment referred to as 3D printer is a device of rapid prototyping technology. It is based on digital model files, using special wax, powdered metal or plastic and other bondable accumulation materials to put data and raw materials into 3D. In the printer, the machine will build the product layer by layer according to the program, that is, the technology of constructing objects by printing layer by layer. This device is often used in mold making, industrial design and other fields to make models or for the direct manufacture of some products. Among them, the 3D printing technology of metal parts is one of the symbolic technologies with a high degree of integration of informatization and mechanization. At present, there are two kinds of successful laser sintering technologies: metal po...
