\"The researchers proved this by shooting a bullet traveling at 5.8 kilometers per second through two cubes. One cube was made from a solid polymer and the other from a polymer printed with a tubulane structure.\
\
The researchers reported that the solid polymer block was left with \"cracks that propagated through the whole structure." The tubulane cube, however, stopped the projectile by its second layer.\"\
\
\"The Rice lab of materials scientist Pulickel Ajayan found tubulanes can be mimicked as scaled-up, 3D-printed polymer blocks that prove to be better at deflecting projectiles than the same material without holes. The blocks are also highly compressible without breaking apart.\
\
As detailed in Small, the discovery could lead to printed structures of any size with tunable mechanical properties.\"
