Description

Technical field [0001] The present invention relates to the field of additive manufacturing techniques, and more particularly to a gradient functional material synthesis and additive manufacturing integrated mechanism. Background technique [0002] The FGM material is different from the uniform materials and composites. It is a material that is used in two (or more) performance and functionality, changing its composition and structure, from a certain aspect (one-dimensional, two-dimensional or three-dimensional) to another. The orientation changes (or quasi-consecutive) change, allowing the performance and function of the material to show gradient non-homogeneous composites, that is, a gradient functional material (FGM), a gradient function type with a gradient function connection, that is, connecting two substrates The interface layer is gradient in gradient; the gradient function coating type, that is, a coating forming a gradient is formed on the matrix material; the gradient ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, most of the powder feeding cabins of additive manufacturing equipment adopt a single powder feeding mechanism, single material powder feeding, and powder spreading; although some use double powder feeding mechanisms, they still use single material powder feeding and powder spreading. To improve efficiency and effect, there is no integrated mechanism and technology for FGM material synthesis and additive manufacturing. This technology is currently blank in China and the market
