    In cooperation with the Sinapore University of Technology and Design, the MIT researchers found a way to print tiny features on a micron scale, and then bent them — causing them to spring back into their original shape afterwards after being heated to a certain temperatures, according to an MIT statement. There are so many potential important applications for the discovery, including actuators that would turn solar panels toward the sun automatically and drug capsules that act on their own. It’s something that goes beyond 3D printing into what researchers would call 4D printing, as the structures cross into the...

    It may seem a touch misleading in name, but scientists at the University of Wollongong say they’re creating what they call 4D printing. The fourth dimension they refer to is time and shape shifting as the researchers have begun to develop 3D printed materials capable of morphing into new structures – post production – as those materials are influenced by the addition of external stimuli such as water or heat. The team at the ARC Centre of Excellence for Electromaterials Science say these new materials are able to transform themselves from one shape into another, and they see applications for...
  • Forget the 3D Printer: 4D Printing Could Change Everything

    Scientists at MIT are using a new technique that could print responsive objects—from water pipes to sneakers—that adapt to their surroundings on their own.These days, 3D printing seems to be at the core of most new new research ventures, whether it's developing ways to print entire meals or recreating facial features to repair a patient's face. But Skylar Tibbits wants to up the ante: He's hoping 4D printing will be the thing of the not-so-far future. The name for his concept, Tibbits admits, was a bit lighthearted at first. At the Massachusetts Institute of Technology, Tibbits and researchers from the...

    The biggest breakthroughs in how we make things lie not in the technology to manipulate materials but in the materials themselves. Such is the thinking behind “4-D printing,” an experimental approach to manufacturing that expands on much-hyped 3-D printing processes. Instead of building static three-dimensional items from layers of plastics or metals, 4-D printing employs dynamic materials that continue to evolve in response to their environment. This new wrinkle in the maker movement comes courtesy of the Massachusetts Institute of Technology’s Self-Assembly Lab, where director Skylar Tibbits and his team are experimenting with so-called “programmable materials.” The researchers print these...
  • Move over 3D printing, self-assemblng 4D-printed materials are on the way

    Molecular self-assembly, whereby molecules position themselves into defined arrangements, is commonplace in biological systems and nanotechnology. But researchers at MIT are working on so called "4D printing" technology that aims to bring the process up to the macro scale, enabling 3D-printed materials to be programmed to self-assemble into predefined shapes and structures. Just imagine buying some flat-pack furniture, bringing it home and enjoying a coffee whilst you watch it assemble itself. This month, Skylar Tibbits, director of the MIT Self-Assembly lab, was named as one of the six Architectural League winners for collaborative research into programmable materials. The 4D printing...
