3D PRINTED TIRE (DIY PROJECT)

pinshape

I started working on this project last week. Would I design my own tires? Of course, why not. For that reason, I began searching for information on photos and videos of new generation tires that don't require air chambers. After finding all the necessary data and diagrams for most common mountain bikes (which is what I have at the moment), I started to design one. However, several factors made it difficult: First, the size of the tire: Unless you have a large format printer that can print in one piece, but that's not the case for all users. For this reason, it was divided into 12 sections, so they can be printed using printers with a base impression of 180mmx180mm. Second, ensuring the printed piece adheres to the Rim: This was a bit more challenging to calculate because the wheels are secured to a metal shaft, or secured with screws to the wheel, or pinned into the interior of the rim. I chose to use two methods at once, the first being making two tabs inside the rim that will catch part of the printed piece so it doesn't come out. The second method was securing it with three plastic ties passing right through the 6mm cavities found in the printed piece. Third, if the tire is divided into 12 parts, how do you join them? This point was or is the most crucial since each printed piece wouldn't rotate on different sides. I thought of using clamps, screws, and even glue, but none of it seemed practical. In the end, I decided to make a cavity in the printed piece with dual purpose: one to save some material and the second to pass a pin that ensures each end of a piece with another. Such that if a piece moves to one side, the part that follows will also move to that side. The materials used for prototyping would be: Tire - Flexible filament; Pin Rin - ABS filament; and Pin Tire - PLA or ABS filament. For a final product, I would use: Tire - Taulman 3D PCTPE, ECO TPU SHORE, Filaflex, Ninjaflex; Pin Rin - Nylon or Taulman filament; and Pin Tire - Nylon or Taulman filament. I think it would be best to print pins with Nylon or Taulman because they have better mechanical properties. And the tire in a rubber-based filament. I believe that not only should this design stay, but it could also be a community project, and what better way to do it than with Pinshade community. For that reason, I leave the link to the original file (http://a360.co/293iBnP), to be studied, modified, and upgraded according to user judgment. Enjoy!
