Incorporating machine learning, MIT engineers have developed a way to 3D print alloys that are much stronger.

The new printable metal can withstand high temperatures and is five times stronger than traditionally manufactured aluminum.

It’s made from a mix of aluminum and other elements that the team identified using a combination of simulations and machine learning, which significantly pruned the number of possible combinations of materials to consider to 40—before identifying an ideal mix.

The team then printed the alloy and tested the resulting material, soon confirming that, as predicted, the aluminum alloy was as strong as any manufactured today.

The researchers envision that the new printable aluminum could be made into stronger, more lightweight and temperature-resistant products
