#3DPrinting #UltraHighStrengthAlloy #MaterialsPowerhouse If it is strong, it breaks; if it is tough, it softens. For thousands of years, there was a curse in metallurgy that no one could break. However, in 2026, Professor Hyung-Sup Kim's research team at POSTECH broke this curse. They turned the honeycomb marks of 3D printing—which everyone discarded as defects—into a weapon. A world record capturing both overwhelming hardness with a yield strength of 1,484 megapascals and ductility of 10%. This single palm-sized metal is changing everything from our airline ticket prices to the space industry and national security. Check out the dramatic reversal of South Korea's materials technology, which has risen from a follower to a pioneer.
