“Our goal is to learn how to 3D print high-performance mechanical components,” he added.

“In essence, we have an autonomous robot that is studying these mechanical systems under our supervision.”

Without AI, optimizing these three properties would be tricky because they can work at cross purposes.

For example, the strongest material may not be the stiffest.

“AI and automated experiments can enable millions of samples to be searched.”

But the AI was able to do it far quicker than a human.

He was not involved in the MIT research.

“This is obviously a remarkable time and cost-cutting technology.”

Eventually, the researchers plan to test the AI process for uses beyond developing new 3D printing inks.

“This has broad applications across materials science in general,” Foshey said.
