3D polymer squeeze

This lump of polymer may look nice and smooth right now, but given a shove it can form complex pasterns of ridges or bumps on its surface—the result of 3D printing the harder, black material within a softer matrix.

The material’s been created by a team from MIT using a 3D printing process to accurately place rigid polymer particles within much more flexible surroundings. When compressed, the differences in stiffness cause the surface to change shape, from smooth to something else altogether. Complex computer modelling enable the team to finely tune the resulting patterns, allowing them to create bumps, ridges and other complex structures on the surface.
