Today’s Spotlight features an image, by Felice Frankel, of a polymer material produced by a 3-D printer.
An MIT team has developed a way of making soft materials, using a 3-D printer, with surface textures that can then be modified at will to be perfectly smooth, or ridged or bumpy, or even to have complex patterns that could be used to guide fluids.
The process, developed using detailed computer simulations, involves a material that is composed of two different polymers with different degrees of stiffness: More rigid particles are embedded within a matrix of a more flexible polymer. When squeezed, the material’s surface changes from smooth to a pattern determined by the spacing and shapes of the implanted harder particles; when released, it reverts back to the original form.
