Researchers from State University of New York at Buffalo and Kansas State University have successfully 3D-printed graphene aerogel.

The material layers up a graphene paste by utilizing 3D printing, ultimately creating complex structures capable of being turned into aerogel.

In order to do that, the team adheres to the following process:

  1. Mix graphene oxide with water to create a paste
  2. The paste is then printed onto a solid platform at -13 degrees Fahrenheit, where it becomes solid
  3. After some time passes, complex structures can be created
  4. The water content is removed from the component after being quenched in liquid nitrogen and       meticulously freeze dried
  5. Finally, the component is heated to remove excess oxygen

And just like that, you have 3D-printed graphene aerogel and all of the good conductivity, extremely low density, and high compressibility that comes with it.

Not only is it almost effortless to craft 3D-printed graphene aerogel into complex shapes, the material only weighs 0.03 pounds per cubic foot!
