mechanical 3d printer
No computers, no motors, just the power of gravity.
The machine uses a 15kg weight to power the mechanism — it does need to be reset during the print, but that’s a small price to pay for this kind of mechanical automation.
we uses a type of clay in a paste extruder that slowly deposits the material on the build platform. To program the machine, there is a small guiding mechanism that follows the contour of a bent aluminum wire. This allows you to make any number of symmetrical and circular objects.
