A kind of gradient material metal mold 3D printing integrated preparation method

Abstract

The invention relates to an integrated preparation method for gradient material metal mold 3D printing. The preparation method comprises the following steps: 1) CAD 3D modeling stage; 2) calculation ratio stage; 3) powder feeding preparation stage; 4) setting laser printing System stage; 5) 3D printing stage; 6) Metal mold post-processing stage: the industrial computer controls the metal powder composition controller of the hopper and the micro-powder feeder of the laser cladding head respectively according to the scanning path of each layered slice Powder feeding, during the powder feeding process, the laser cladding head of the laser printing system performs laser cladding on the metal powder layer by layer to form a three-dimensional metal mold forming part with a material gradient. The preparation method has the advantages of simple and easy operation, high precision, low preparation cost, short preparation time, long service life of the mold, high mechanical performance, high mold comprehensive performance and the like.

Description

technical field [0001] The invention relates to the technical field of manufacturing metal mold forming materials, in particular to an integrated preparation method for gradient material metal mold 3D printing. Background technique [0002] Gradient materials have been paid more and more attention in the field of material technology because of their own characteristics of continuous or accurate continuous change in structure and performance in the direction of material thickness or length. At present, many scientific researchers and enterprises in the world attach great importance to it and carry out in-depth research on it. Up to now, some basic research methods have been explored and many systems of gradient materials have been prepared. Common gradient material preparation methods include powder molding preparation method, physical vapor deposition preparation method, chemical vapor deposition preparation method, plasma spraying preparation method, electroplating method, ...

AI Technical Summary

Problems solved by technology

Common gradient material preparation methods include powder molding preparation method, physical vapor deposition preparation method, chemical vapor deposition preparation method, plasma spraying preparation method, electroplating method, etc.; however, although these preparation methods have their own advantages, they also have some limitations. For example, it is difficult to achieve continuous and uniform change of material components in the powder molding preparation method, and it is difficult to obtain thick materials by the vapor deposition preparation method, etc.

The process equipment of these preparation methods is also relatively complicated, and the preparation process is relatively cumbersome. In addition, there are disadvantages such as waste of precious element usage, low precision, and relatively poor mechanical properties in the manufacturing process.
