Video PlayerClose SYDNEY, Dec. 5 (Xinhua) — A new range of high-performance titanium alloys developed by Australian scientists, is being described as a major breakthrough that could change the face of 3D printing technology. With the potential to be used in advanced military and aerospace applications, as well as medical devices such as surgical robots, the successful trials focused on titanium-copper alloys. Carried out by the Royal Melbourne Institute of Technology (RMIT), the Australian Government’s scientific body — CSIRO, the University of Queensland and the Ohio State University in the United States, details of the collaborative research project were published in the journal Nature on Thursday. Opening the door to a “new breed of alloy” that could also increase manufacturers’ production rates, current titanium alloys used in additive manufacturing can often cool and bond together in “column-shaped crystals during the 3D printing process,” which can leave the material prone to cracking and distortions. This is because, unlike commonly used metals such as aluminium, there are no commercial grain refiners for titanium that allow manufacturers to effectively refine the microstructure of the metal to avoid these issues. But according to Professor Mark Easton from RMIT University’s School of Engineering, the “exceptional… Read full this story
