Title:
3D PRINTING DEVICE AND METHOD BASED ON CENTRIFUGAL ATOMIZATION
Document Type and Number:
WIPO Patent Application WO/2021/052069
Kind Code:
A1
Abstract:
A 3D printing device and method based on centrifugal atomization, the device comprising a smelting system, a cabin (3) having a sealed cavity, a turntable (20), a guide sleeve (18), and a three-dimensional motion platform having a molten metal receiving unit (7), and a control unit for controlling the three-dimensional motion platform. Metal raw materials enter the sealed cavity after being smelted, and are atomized and thrown out in the circumferential direction due to the rotation of the turntable; the atomized molten metal passing through spray gaps (24) in the guide sleeve adheres to the receiving unit of the three-dimensional motion platform; and the control unit controls the movement of the three-dimensional motion platform to change the position where the receiving unit receives the molten metal to form workpieces of different shapes. According to the 3D printing method based on centrifugal atomization, during the entire printing process, the metal raw materials are directly melted and atomized, and then stacked and solidified, and only by controlling the solidification speed of the metal raw materials, the internal structure of the output workpieces can be more dense and uniform, thus improving the production efficiency.
