The Thread is Made up of 70A Polyurethane. We got Polyurethane Tubing of 4" OD x 3"ID 70A Polyurethane and cut it to 1" slices. Then cut the ID to 3.25" and make a .125" wide cut for the Lip of the rim to rest on. |

Re: Custom Wheels
That's pretty neat. How is the tread kept from spinning around the wheel? Friction?

Re: Custom Wheels
Here is our 2014 version of our 3D printed wheels. We integrated the tread from vex pro.
We were fairly happy with them. They are made on a uprint plus, ABS solid. We would get two pairs on a print in about 10 hours. We basically used the same profile from VexPro CAD and built a wheel around that. http://www.chiefdelphi.com/media/photos/40594? Last edited by Metalcrafters : 05-05-2014 at 19:40. |

Re: Custom Wheels
The tread is held with friction and compression; We compress the tread slightly onto one rim and then sandwich the other rim on top just like a "sandwich" or "oreo".

Re: Custom Wheels
As mentioned by Eric this material is polyurethane 70A. The nice thing about ordering polyurethane is it comes in several colors. One factor that was key to selecting this material is that the material for our wheel had to survive our 2+ mile walk in the parade.
Here's an image of a complete wheel. |

I like the idea of not having to continuously replace the wheel for demos and such. |
