The second half of the process is 3D printing the wheels to which the tires will be attached. These will be much smaller than the original 3D printed component, and fit inside of the silicone mold.

[Michael Rectin] is in on the action, and he’s been exploring how to 3D print a decent set of tires to help his RC car reach higher speeds mph. His first efforts involved experiments with TPU.

Faster, easier, and cheaper than the molded techniques of the past, 3D-printed technology allows racing teams to grab a ...

Because of how the wheel rolls, your 3D-printed rider will pedal backwards ... Instead, you have to use thermoplastic polyurethane (TPU) extruded from a 0.4 or 0.6mm nozzle. And most importantly ...
