At the TED conference in Los Angeles, architect and computer scientist Skylar Tibbits showed how the process allows objects to self-assemble. It could be used to install objects in hard-to-reach places such as underground water pipes, he suggested. It might also herald an age of self-assembling furniture, said experts. Smart materials TED fellow Mr Tibbits, from the MIT's (Massachusetts Institute of Technology) self-assembly lab, explained what the extra dimension involved. "We're proposing that the fourth dimension is time and that over time static objects will transform and adapt," he told the BBC. The process uses a specialised 3D printer made by Stratasys that can create multi-layered materials.
