Revolutionary Titanium Metamaterial: Enhanced Strength and Versatility via 3D Printing

Researchers at RMIT University have developed a groundbreaking metamaterial made from a common titanium alloy that exhibits exceptional strength and lightness. Published in the Advanced Materials journal, the material’s lattice structure design enhances its strength, distributing stress evenly and reducing weak points. Utilizing metal 3D printing technology, the researchers optimized a hollow tubular lattice structure, making it 50% stronger than the strongest alloy of similar density used in aerospace applications.

The design also deflects cracks, enhancing toughness. The material has promising applications in various fields, from medical devices to aerospace parts. While its adoption may take time due to limited availability of the technology, the team welcomes collaborations for further development and real-world applications.
