Electrolytic etching electroplating accumulation three-dimensional (3D) printer

Abstract

A three-dimensional (3D) printer is characterized by comprising an X-axis track frame (1), a Z-axis track frame (2), a Y-axis track frame (3), a universal numerical control steering frame (4), a conductive base plate (5), a coaxial sleeve printing head (6) installed on the universal numerical control steering frame (4), a backflow outer hose (7) connected with an outer tube of the coaxial sleeve printing head (6), an automatic-flowing inner hose (8) connected with an inner tube of the coaxial sleeve printing head (6), a storage tank (9) containing electrolyte, a metal electrode block (10) and a numerical control sucking pump (11) installed at the tail end of the backflow outer hose (7) and used for sucking the electrolyte into the storage tank (9). The metal electrode block (10), a electrolyte solution, the conductive base plate (5) and a direct-current power supply of the 3D printer form an electrolysis device, the electrolyte solution is electrolyzed on the conductive base plate (5), and a precipitated metal coating serves as an accumulation printing material. The shortcoming of lower printing efficiency of a 3D printer in the prior art is overcome, the accumulation printing material is low in price, an etching and accumulation method is simple, and the electrolytic etching electroplating accumulation 3D printer is high in printing speed.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an electrolytic etching electroplating stacking 3D printer. Background technique [0002] 3D printer, that is, a machine of rapid prototyping technology, is based on a digital model file, using powdered metal or plastic and other bondable materials, and superimposing "printing materials" layer by layer through computer control, and finally The blueprint on the computer becomes a physical object, which is a technique of constructing objects by layer-by-layer accumulation. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacturing of some products, which means that this technology is becoming popular. [0003] There are various forms of stacking thin layers by 3D printers. Some 3D printers use the "inkjet" method, using the printer nozzle to spray a very thin layer of liq...
