Every passionate mountain biker knows how quickly a flat tire can ruin a mountain bike trip or even cause an accident. While airless tires have long seemed like an unattainable technology of the future, the creator of [Berm Peak] decided to put the matter to the test. He made his own working bicycle tire on a home 3D printer.<\/p>\n\n\n\n
After some initial experimentation, he designed a model made of flexible TPU material. The key part of the design was a durable S-shaped structure that extends between the outer tread and the rim itself, mimicking the pressure of a standard tire. The entire product was printed in several separate parts, which were then attached to the wheel rim using a specially printed interface.<\/p>\n\n\n\n
Mountain biking is an extremely challenging environment for such designs, but the final product proved surprisingly durable in a demanding off-road test. This is an extremely nice achievement for a home-made project. The latter of course raises the question of what specialized tire manufacturers could achieve in this area.<\/p>\n\n\n\n
Despite the success of this project, there is some healthy skepticism about whether such tires will ever truly dominate the market. Today, most mountain bikers already use tires with a sealing fluid (the so-called \u201ctubeless\u201d system), which solves puncture problems very effectively. Nevertheless, the printed bright green tire without air is a very interesting and ambitious project that has attracted a lot of attention on the bike paths.<\/p>","protected":false},"excerpt":{"rendered":"
