This approach could be useful anywhere there’s a need for a combination of high stiffness (for load bearing), high strength, and light weight — such as in structures to be deployed in space
What’s the difference between the Eiffel Tower and the Washington Monument?
Both structures soar to impressive heights, and each was the world’s tallest building when completed. But the Washington Monument is a massive stone structure, while the Eiffel Tower achieves similar strength using a lattice of steel beams and struts that is mostly open air, gaining its strength from the geometric arrangement of those elements.
Now engineers at MIT and Lawrence Livermore National Laboratory (LLNL) have devised a way to translate that airy, yet remarkably strong, structure down to the microscale — designing a system that could be fabricated from a variety of materials, such as metals or polymers, and that may set new records for stiffness for a given weight.
