China Announces Development of New Metal 3D Printing System

metal 3d printing

Little by little China is becoming one of the most technologically advanced countries. Among his latest discoveries to highlight the work carried out by a group of researchers from the Huazhong University of Science and Technology, located in the province of Hubei, in central China, which have successfully developed a new technology with which to create metal parts and molds by 3D printing.

Apparently, this new methodology would solve all the problems that metal 3D printing has today com can be the flowing, dripping or crumbling of molten materials due to gravity, cracks, stress and rapid heating and cooling process. Problems that, as has been demonstrated countless times, can severely affect modeling performance and accuracy.

Chinese researchers talk about the development of a new metal 3D printing technology

As explained by those responsible for this project, it seems that this new method combines casting technology with metal casting. Thanks to this, the strength and ductility of metal molds have been significantly improved to extend their life and reliability. As a detail, tell you that this new technology has been baptized by its creators with the name of «micro casting and smart casting«.

The invention also reduces casting equipment and raw material costs, using a metallic filament instead of powder. For this, a computer-controlled modeling process must be used. According to the team in charge of the development of this new technology, also allows to create thin metal walls, something that in metal 3D printing SLS / SLM technologies usually brings quite a lot of problems.
