3D-Printed Electric Marble Mazes

Maker Faire Bay Area 2023

October 13th-22nd

We have a variety of battery-powered 3D printed marble machines that we'd like to exhibit.

Each model is 3D printed using PLA plastic on consumer FDM printers. This takes anywhere from six to fifteen hours, depending on each model's size and complexity. A model is made from two to seven PLA parts, which are inspected and cleaned of any residual plastic that's a byproduct of the printing process. (None of the models require support material, which simplifies the cleaning process). Once the PLA parts are prepared they, along with the electric parts are assembled into complete models. There's no painting — the plastic is the color it appears.

The models are designed in Blender. They use a variety of different mechanisms to lift the marbles.
