PRINTED device DOES nothing up until THE warm death OF THE world

A 2:1 gear reduction slows down a spinning shaft to half speed as well as doubles the torque. Repeat this a few times, as well as you’ve got a ludicrous amount of torque moving as well slowly to see with even precision instruments. That’s the concept behind [Jeshua]’s project, a printed device partially embedded in a block of concrete.

[Jeshua]’s develop is a replica of one of [Arthur Ganson]’s kinetic sculptures. [Ganson]’s device utilizes 50 sets of gears to decrease the rotation of 200 RPM motor much more that 200  quintillion times. The final gear in the sculpture is embedded in a block of concrete, waiting to be freed by either erosion of the concrete block or the sun going nova.

Instead of metal gears, [Jeshua] utilized 3D printed gears in PLA. After assembling them on a stand, he cast concrete around the final, barely moving gear. It’s an impressively useless develop that will turn to dust before the final gear makes even 1/10th of a revolution. This device might have a longer life if it were printed with ABS instead of PLA, however with the time scales we’re speaking about right here it won’t make much difference.
