Zip it good, science edition
A Zipper Patent Sat in a Garage for 40 Years. Now It's Real
MIT finally built a forgotten garage zipper, and the internet can’t decide if it’s genius or glorified plastic
TLDR: MIT revived a 40-year-old garage invention: a three-sided zipper that can turn floppy shapes into stiff ones with a pull. Commenters are torn between calling it a clever breakthrough, questioning whether it’s actually strong enough to matter, and making delightfully weird space-spaghetti jokes.
A rejected 1985 idea just staged the most dramatic comeback in maker-history fashion: Bill Freeman, then at Polaroid and now a professor at the Massachusetts Institute of Technology, shelved a strange three-sided zipper in his garage for nearly 40 years. Now MIT’s Computer Science and Artificial Intelligence Lab has turned it into the Y-Zipper, a printable design that lets something go from soft and bendy to stiff and useful with one zip. That alone had commenters split between “future of engineering!” and “okay, but is it actually better than a normal beam?”
The loudest skeptics were not buying the hype, with one commenter bluntly wondering whether the “rigid” and “load-bearing” claims would be much worse than a regular beam of the same size. Translation: cool demo, but can it really carry weight, or is this just science-fair glamour? On the other side were the dreamers, instantly launching into sci-fi mode and imagining satellites arriving in orbit as a “tightly packed box of spaghetti” before unfurling into useful shapes. Yes, the comments went from garage patent to space noodles in record time.
And then came the side drama: one user said the write-up itself “reads like it’s been machine generated,” while another practically begged everyone to watch the MIT video before judging. Bonus snark arrived via a wink at zipper giant YKK, as if the humble zipper were suddenly entering its messy reboot era. The vibe? Half awe, half roast, fully entertained.
Key Points
- •Bill Freeman conceived and patented a three-sided zipper in 1985, but the prototype remained unused for decades after being rejected in a design competition.
- •MIT CSAIL researchers later developed the concept into the Y-Zipper, a 3D-printed fastener that transforms flexible strips into a rigid, load-bearing triangular beam.
- •The Y-Zipper is reversible: zipping creates rigidity, while unzipping returns the structure to a soft and pliable state.
- •CSAIL built a software-driven design workflow that lets users customize strip length, bend angle, and four motion configurations before automated 3D printing.
- •The article says the team demonstrated applications in camping gear, medical equipment, robotic limbs, and art installations, while exploring stronger materials and larger-scale structures.
