Chinese scientists develop new metal 3D printing technology  

Researchers in central China’s Hubei province have successfully manufactured metal parts and molds using new 3D printing technology. The new metal 3D printing technology addresses existing problems in traditional metal 3D printing methods, said Zhang Hai’ou, leader of the 3D printing technology research team at the Huazhong University of Science and Technology. These problems, such as flowing, dropping or crumbling of fused materials due to gravity, cracking, stress and rapid heating
