Other AbstractThe invention relates to a coaxial powder feeding system of laser rapid prototyping preparation function gradient material, comprising a powder inlet device, and the powder is absorbed and conveyed by carrier gas. The powder inlet device is communicated with a powder mixer through a first conveying pipe. The powder mixer is used for mixing the powder which has been conveyed. The mixed powder enters into a powder separate device through a second conveying pie. The powder separate device is used for separating the mixed powder into multi-path. The powder separate device is communicated with thepowder inlet of a nozzle through a third conveying pipe. The nozzle makes the multi-path powder flock together in a molten pool formed by laser. The function gradient material is prepared under the cladding action of laser and powder. The mix of the powder is uniform. The coaxial powder feeding system has good power feeding property, which can realize the optimum processing, and at the same time,can be suitable for different processing distances. The powder utilization rate is high. The manufacturing accuracy is good. At the same time, the powder conveying distance can be adjusted with a certain scope, and so the coaxial powder feeding system can not be limited to the manufacturing space.
