Ultrauniform, strong, and ductile 3D-printed titanium alloy through bifunctional alloy design. (https://pubmed.ncbi.nlm.nih.gov/38330109/)

These scientists wanted to make better and stronger metal objects using a special kind of printing called 3D printing. When they used 3D printing, the metal objects sometimes had problems. The metal had big grains and different parts of the metal had different properties. This made the metal weaker and not as good.

But the scientists found a way to fix this problem. They used a special metal called Ti-5Al-5Mo-5V-3Cr and added tiny particles of molybdenum (Mo) to it. When they printed this metal with the molybdenum particles, something really cool happened. The metal grains became smaller and the different parts of the metal became more similar. This made the metal stronger and better.

So now, the scientists have found a way to make metal objects using 3D printing that are really strong and have the same properties all over. This is important because it means we can make better things using 3D printing.
