Aluminum in 3D?

At MIT aluminum has been made 5 times stronger through the use of 3D printing. Aluminum is a type of alloy, a mixture of two or more metals, which typically has advanced properties. 

So, what are the implications of this discovery?

With a lighter material, less energy will be needed for transportation purposes without losing any stability in the process due to a higher strength. 

John Hart, head of MIT’s Department of Mechanical Engineering has been quoted, "Because 3D printing can produce complex geometries, save material, and enable unique designs, we see this printable alloy as something that could also be used in advanced vacuum pumps, high-end automobiles, and cooling devices for data centers."

With this known technique, the engineers at MIT can now look to other alloys to refine properties of other alloys and metals.
