New tech improves metal 3D printing
Print Edition
RESEARCHERS with Huazhong University of Science and Technology 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, Zhang Hai’ou, leader of the 3D printing technology research team at the university, said yesterday.
These problems, such as flowing, dropping or crumbling of fused materials due to gravity, cracking, stress and rapid heating and cooling can severely affect modeling performance and accuracy, Zhang said.
The method combines metal casting and forging technology and significantly improves the strength and ductility of metal molds to expand their life and reliability.
