Novel active mixing and switching printheads enable 3D printing of complex fluids and gels

Three dimensional printing is revolutionizing the production of new devices and structures, including soft robots, flexible electronics and engineered tissue replacements, but advances have been challenged by the inherent complexity of integrating multiple materials. Now, breaching the next frontier in 3D printing, Jennifer A. Lewis, Sc.D., has designed new systems to actively mix and print concentrated viscoelastic inks that, for the first time, allow for the simultaneous control of composition and geometry during printing.

MIT Researchers 3D print synthetic spider webs to help design materials with high strength & low density

Of all of the things in the natural world, spider webs have consistently been one of the more fascinating biological structures known to man.  Between its high-strength properties (ounce for ounce it’s stronger than steel) to its complex mathematical patterns, the spider’s web is nothing short of one of nature’s most impressive structures.   Continue reading “MIT Researchers 3D print synthetic spider webs to help design materials with high strength & low density”
