In simulations of a porous, gyroid-like graphene architecture, researchers reported a sample with 5 percent of steel’s density and 10 times its strength. The result depended on the structure’s geometry, and it was not a direct, like-for-like test of a full-scale graphene object against steel.
What MIT reported about the material
In a January 6, 2017 report, MIT described a team’s designed three-dimensional graphene architecture: small graphene flakes compressed and fused into a sponge-like form with a gyroid-like geometry. The researchers’ paper appeared in Science Advances. MIT’s own headline was qualified: “Researchers design one of the strongest, lightest materials known.”
MIT research scientist Zhao Qin described one modeled sample as having “5 percent the density of steel, but 10 times the strength.” Those figures refer to the researchers’ reported result in the study’s simulation context; they do not establish a universal ranking across every material, shape, and test condition.
How the researchers assessed the design
The team made enlarged models of the configurations with a high-resolution, multi-material 3D printer, mechanically tested their tensile and compressive properties, and simulated their mechanical response. MIT reported that the tests and simulations matched. The models were not full-scale graphene objects, and the report does not describe an identical, direct comparison against a steel object.

The printer’s role was to model and test the geometry. The report does not identify a printer model or establish that a consumer printer can produce graphene or reproduce the study.
Why geometry mattered
The finding centered on architecture as much as composition. Curved surfaces and the gyroid-like form distribute loads efficiently. MIT compared the principle to shaping a sheet of paper into a tube, which makes it stronger in one direction than a flat sheet. Markus Buehler, then head of MIT’s Department of Civil and Environmental Engineering, said: “The geometry is the dominant factor. It’s something that has the potential to transfer to many things.”

That means the reported performance should not be read as a property of graphene alone. MIT said the design principles might also be applicable to materials such as polymers or metals; that is a proposed transfer of the geometry, not evidence that those materials have already achieved the same measured result.
What the work might—and might not—be used for
MIT’s 2017 report suggested possible future uses in applications where strength and low weight matter, including structural materials for bridges, insulation, and filtration. These were possibilities discussed by the researchers, not products or deployed infrastructure.

That rules out the notion of using an ultralight version as a durable helium replacement for balloons.

MIT’s February 2022 spotlight concerned a separate polymer material described as stronger than steel and as light as plastic. It is not the 2017 porous graphene architecture, so the materials, dates, and claims should not be combined. MIT’s 2022 spotlight covers that distinct work.
