Osaka University proposes a new method to control the performance of 3D printed alloys Professor Hiroyuki Yasuda, Associate Professor Yanzhun Zhao, and graduate student Aoi Yamashita, along with other researchers at Osaka University, announced on the 11th that they have discovered a method to manufacture nickel-based superalloys with higher strength than traditional materials using Laser … Read more
In simple terms, 3D printed aluminum alloy parts are prone to cracking under sudden impact, making them not “sturdy” enough. Researchers found that changing the laser scanning method during printing—re-melting each layer at a faster speed and higher power after printing—can refine and homogenize the metal grains inside the parts, effectively weaving a stronger “net” … Read more
Researchers at IMDEA Materials Institute have developed a new process to predict and control the microstructure of nickel-based high-temperature alloys during the metal 3D printing process. The team created a tool that allows manufacturers to control the metal grain structure by adjusting parameters such as laser power, scanning speed, hatch line distance, and scan length. … Read more
By achieving localized control of the grain structure, engineers can design components with superior performance. This research not only advances the development of materials engineering science but also creates opportunities for innovative component design in various fields such as aerospace, power generation, and space exploration. [Qiming Additive Manufacturing] Nickel-based superalloys are renowned for their exceptional … Read more
