A 1985 idea that seemed impossible to revive thanks to 3D printing: a “triangular cremallera” capable of moving from flexible to rigid in seconds. MIT has made it a reality and already imagine applications in robotics, medical splints, drop-down shelters or even space technology. The Y-Zipper resisted more than 18,000 cycles in testing labels: science, mit» original news (www.microsiervos.com)

This triangular zipper that they have reinvented in the M.I.T. is actually an idea proposed in 1985 by Professor William Freeman. An advance to its time, because at that time manufacturing it was extremely expensive and complicated, almost impossible. Today, thanks to 3D printing and design software it has been possible to become a reality and is much cheaper and viable. Its pieces are printed in 3D and are resistant; in the tests it survived 18…
