Marcus Wu’s 3D-Printed Curta Calculator

Adam walks us through his collection of analog calculators, culminating in one of his newest favorite objects: a 3D-printed Curta calculator that’s a perfect scaled reproduction of the intricate mechanical computer. This incredible replica was engineered and built by Marcus Wu, who started the project two years ago.

  1. That’s an astounding machine. Well done Marcus.
    What was that Radiolab where “nothing we’ve ever invented has stopped being made?”

  2. That is one of the most beautiful 3D machines I’ve ever seen, I love, looooooove functional 3D parts and this is the summum of that.

    Would’ve been nice to see it calculate something, no idea how it should work. 🙂

  3. If you love mechanical calculators, and find yourself in Bonn, Germany, the “Arithmeum” may be worth checking out. It is a museum that houses the private collection of a former math professor of the university of Bonn, Professor Korte. Apart form calculators, it also houses a collection of modern art, and the building itself is worth a look, too.

  4. Oh man, how I want a Curta of my own. Hadn’t even considered 3d printing to make my own. My dream project for someday is to 3d print my own Antikythera mechanism

  5. Interesting. Pretty amazing piece of machinery given the original size. Would be interesting to machine one to the original drawings. Maybe someday.

  6. Thank you! Didn’t remember that one. Awesome to see it work, so.. as read on a actual funny (amazing) Youtube comment; what happens if you divide by 0? 🙂

  7.   I have spent hours watching YouTube videos of electro mechanical calculators freaking out when dividing by zero 😉
