One of the killer apps of 3D printers is the ability to make custom gears, transmissions, and mechanisms. But there’s a learning curve. If you haven’t 3D printed your own gearbox or automaton, here’s ...

Have you ever seen a flag being raised, or wondered how a mechanical clock works? Let’s take a look at some of the simple mechanisms that they use. Pulleys and gears. When a flag is raised, it will ...

There was a time, not so very long ago, when simply getting a 3D printer to squirt out an object that was roughly the intended shape and size of what the user saw on their computer screen was an ...

A gear close gearA gear is a mechanical part with teeth that interlock with another gear or belt to transfer motion and power while changing speed, or direction in a mechanical system. is a special ...

Courant researchers found a way to create gear mechanisms using water through fluid mechanics — how liquids and gases interact with themselves and other objects.  Published in Physical Review Letters, ...
