An additive manufacturing device for improving the utilization rate of precious metal powder and a processing method thereof

Abstract

The application provides an additive manufacturing device for improving utilization rate of precious metal powder and a processing method thereof, which comprises a laser emitting device, a powder laying device, a processing lifting platform assembly, a shaping device, a scraper and a base; the processing lifting platform assembly is installed on the base and vertically linearly moves through a lifting platform ball screw; the shaping devices are respectively arranged on both sides of the ascending path of the processing lifting platform assembly; the shaping rods horizontally move through ball screws; each shaping rod is internally provided with a powder recycling cabin, and each powder recycling cabin is in communication with a powder recycling box; an outer baffle is installed above the base, a moving platform is installed on the outer baffle, and the scraper vertically installed on the moving platform. The device can limit and position the laid powder to a specified shape in one device and then perform laser additive manufacturing, effectively improves the utilization rate of the precious metal powder, recycles the excess powder, improves the powder utilization rate and reduces the production cost.
