MIT researchers have been able to use graphene to print 3D objects with a geometry that has 10 times the strength of steel but only a fraction of the wieght.
The discovery using the strongest material there is has the potential to enable lightweight products for airplanes, cars, buildings and even filtration devices because of the printed objects' porous designs.
In its typical two-dimensional, flat state graphene is only one atom thick, so like a sheet of paper it is flimsy and easily torn. But, graphene also conducts electricity efficiently and is nearly transparent.
Until now, researchers struggled to use graphene's two-dimensional strength in three-dimensional materials.
