This 3D-printed surface which was developed, depending on the situation, can be either smooth, bumpy, ridged, or channeled, and even better yet is its ability to dynamically change texture thanks to the application of pressure. Is there any practical application in such a surface? Well, mutable surface textures are useful when it comes to preventing unwanted animals from growing on ship hulls, or perhaps to channel microscale amounts of fluids, or to use it in the camouflage creation process, as well as optics. Even more important, surfaces that are created by the MIT team happen to be produced using a 3D printer, which means it will be all the more easier to be creative with this particular technique.
