Description
Technical Field

Background
At present, the metal 3D printing method mainly comprises the following steps: the selective laser melting, the electronic selective laser melting and the like are mostly performed by sintering or bonding materials together and then stacking the materials layer by layer, so that the purpose of forming is achieved. However, the melting temperature of the metal material is higher, the printing head needs to be designed to be more resistant to high temperature, internal stress is generated during solidification due to the need of rapid cooling, and the formed part is easy to crack, deform, have air holes and other problems, and the method has the defects of low processing precision, poor surface quality, expensive equipment and materials and the like. The invention realizes 3D printing by electrodeposition, and the electrodeposition does not need heating or only needs temperature of dozens of degrees, so the invention can not generate the stress problem caused by high-temperature rapid cooling.
The jet electrodeposition technology is based on a high-speed jet flow, when the jet electrodeposition technology works, an anodized electrolyte beam ejected from a nozzle at a high speed impacts the surface of a cathode, and meanwhile, metal ions in the electrolyte beam are reduced into atoms and accumulated on the cathode under the action of an electric field, so that selective electrodeposition processing is realized, and the forming precision, the appearance quality and the tissue structure of the technology hardly reach the expected targets. A great disadvantage of this technique is the high technical requirements for printing relatively large parts, which are not present in the case of the present invention.
Electroforming is a modern processing technology for preparing products based on the principle of metal ion cathodic electrodeposition, so that metal ions in a solution migrate to a cathode under the action of an electric field to obtain electrons, the electrons are reduced into atoms, the atoms are deposited on the surface of a cathode master mold, and the surface of the cathode master mold is demolded, thereby manufacturing the products identical to the master mold. The invention is similar to electroforming, and the invention prints by arranging a mask on the anode, thus not only the demoulding is not needed, but also the problems of uneven deposition and the like caused by the distribution characteristics of the processing electric field can be solved.
Namely, the film deposition technology, is a technology which can selectively electrodeposit a metal structure layer at a high speed in real time on the basis of mask deposition, and the technology is easy to obtain ultra-thick micro electrodeposition, but the defect of the technology is obvious, and the technology can only print a single model and has obvious defect for a complex structure.
