Problems solved by technology

[0004] The disadvantage of this method of powder usage is that it is inefficient and a large amount of powder cannot be used for production
After processing, the excess powder should be recovered, sieved, removed, and reused, which increases the processing cost

Abstract

The invention relates to a powder system device and method for improving the power utilization efficiency in an additive manufacturing process, the device comprising a spatially movable powder spreading device (20) for powder, a powder system (35) for providing powder, and a control unit (50) for controlling at least the powder spreading device (20) and the powder system (35), wherein the powder system (35) comprises at least a first powder container (36) and a second powder container (39), which are arranged to alternately act as a temporary powder supply container (33) and a temporary powder overflow container (38) respectively.

Description

technical field [0001] The invention relates to a device using a powder system through additive manufacturing technology, and a processing method for using the device to form complex structural workpieces. Background technique [0002] Additive manufacturing technology, or 3D printing, builds complex structural workpieces by using powder as raw material. The powder material is melted by high-energy beam focusing, and solidified again to obtain a specified spatial configuration. Known metal additive manufacturing processes are laser powder bed fusion (LPBF), electron beam melting or selective laser sintering. In the LPBF process, the material to be processed is deposited in a thin layer on the substrate platform by the powder spreading system of the equipment in the form of powder. The powder material is completely melted and solidified locally under laser focused melting, forming a nearly two-dimensional solid configuration. Then the substrate platform is lowered by subsi...
