Patent number: 11420257Abstract: An apparatus for efficiently preparing spherical metal powder for 3D printing includes a housing, a crucible and a powder collection area arranged in the housing, wherein a turnplate arranged in the collection area is an inlaid structure. A material having a poor thermal conductivity is selected as the base of the turnplate, and a metal material having a wetting angle less than 90° with respect to droplets is selected and embedded into the base to serve as an atomization plane of the turnplate. An air hole is disposed in the turnplate. The spherical metal powder for 3D printing combines electromagnetic force breaking capillary jet flow and centrifugal atomization, which breaks through the traditional metal split mode, and makes the molten metal in a fibrous splitting.Type: GrantFiled: September 25, 2019Date of Patent: August 23, 2022Assignees: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Wei Dong, Yao Meng, Sheng Zhu, Xiaoming Wang, Yang Zhao, Yanyang Wang, Fumin Xu, Zhaofeng Bai, Yang Han, Guobin Li, Wenyu Wang, Qing Chang, Zhiqiang Ren, Jing Shi, Guofeng Han, Tao Teng, Yu Sun, Zhiyong Qin
