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 process (with the 4th dimension being self-assembly over time) involves the use of materials that change their shape in response to movement or environmental factors, such as the presence of water, air, and/or temperature changes.
