MIT researchers revive 40-year-old triangular zipper concept now made possible by 3D printing, creates shape-shifting robots and deployable structures — 3D-printed 'Y-Zipper' turns floppy tentacles in

Summary

MIT researchers revived a 40-year-old concept to create a 3D-printed 'Y-Zipper.' This mechanism transforms floppy structures into rigid beams, enabling shape-shifting robots and deployable frameworks.

Key Takeaways

1. Researchers at MIT's Computer Science and Artificial Intelligence Laboratory have developed a three-sided zipper that transforms 3D-printed floppy structures into rigid, load-bearing forms in seconds.
2. The Y-Zipper joins three flexible arms into a rigid 3D triangular tube, switching between soft and rigid states relevant for robotics and deployable systems.
3. The concept originated in 1985 with MIT professor William Freeman, who proposed a triangular zipper system, but manufacturing limitations made the design impractical until modern 3D printing.
