It would make sense that a complex structure that mimics the molecular structure would be stronger per unit of mass than a lump of the same material, in the same way that a simple i-beam or a truss is stronger that a solid rod of steel in specific design applications. In both cases, its strength where you need it; nothing where you don’t
Really neat stuff.
- goodSteveramos 3y agoDo you think this team invented that idea? Im struggling to understand how large their contribution is.
- JumpCrisscross 3y agoWe haven’t been able to fabricate relatively perfect metal crystals in most metals until recently.
- goodSteveramos 3y agoI dont this the object they manufactured is monocrystaline. Its a part made with a commercial laser sintering 3d printer
- orev 3y agoThe point they’re making is that since making a monocrystaline material is difficult, it can be emulated by using a metamaterial structure that confers similar properties.
