Title:
METAL 3D PRINTING DEVICE AND METAL 3D PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/205655
Kind Code:
A1
Abstract:
A metal 3D printing device (100), comprising a forming table (100a), a first powder spreading arm (10), a second powder spreading arm (20), a wind field mechanism (30) and a scanning mechanism (40), wherein the forming table (100a) is used for bearing a powder; the first powder spreading arm (10) and the second powder spreading arm (20) are arranged spaced apart and can move in a direction parallel to the forming table (100a) so as to respectively spread powder to the forming table (100a); the wind field mechanism (30) comprises an air blowing port (31) and an air collecting port (32), the air blowing port (31) is provided on the first powder spreading arm (10) and blows air to the forming table (100a), and the air collecting port (32) is provided on the second powder spreading arm (20) and sucks in air; and the scanning mechanism (40) is used for emitting a laser to the powder between the first powder spreading arm (10) and the second powder spreading arm (20), such that the powder is solidified to form a component. The metal 3D printing device (100) achieves the aim of printing while spreading powder, thereby improving the printing efficiency. Also provided is a metal 3D printing method, which can also achieve the aims of continuous powder spreading and continuous printing, thereby improving the printing efficiency.
