Creating RC car tires using 3D printing technology to achieve high speeds.

The RC world on YouTube has become a hotbed of innovation and competition, particularly in the realm of high-speed racing. One enthusiast, Michael Rectin, has taken it upon himself to push the boundaries of what is possible with his RC car. His latest endeavor has been to 3D print a set of tires that will allow his car to reach even higher speeds.

Rectin’s first attempts at creating 3D printed tires involved using TPU, a popular filament among 3D printing enthusiasts. While the tires looked decent, they lacked traction, which resulted in poor performance on the track. Undeterred, Rectin decided to try out VarioShore TPU, a filament known for its versatility in delivering different properties depending on the printing method.

After some experimentation, Rectin was able to create a set of sporty-looking tires that offered a significant improvement over off-road RC tires. One major advantage of his design was that it did not experience significant ballooning as the rotational velocity of the wheels increased. This meant that Rectin could achieve higher speeds without sacrificing stability.

However, there was one area where Rectin’s 3D printed tires fell short: grip. Compared to off-the-shelf rubber RC tires designed for high-speed use, the VarioShore material simply did not provide the same level of traction. Additionally, the commercially-available tires offered a smoother ride, further highlighting the limitations of 3D printed tires.

To compensate for the lack of grip, Rectin employed some clever techniques for high-speed RC driving. He modified a flight controller to correct the car’s steering in response to any disturbances, ensuring that it stayed on track even at high speeds. He also implemented a scaling method that reduced steering inputs as the car reached higher speeds, minimizing the risk of overcorrection.

Despite these creative solutions, some crashes and mishaps were inevitable. In some instances, the wheels were thrown off in spectacular tumbling crashes. While electric-powered RC cars have certainly become incredibly fast, there may come a point where even they cannot break records. Perhaps it’s time to consider jet power if one truly wants to push the limits of speed.

Rectin’s efforts to create 3D printed tires are undeniably impressive, considering the fact that tire technology is a billion-dollar industry with closely guarded secrets. The ability to print functional tires with just two off-the-shelf filaments is certainly a hack in its own right. It will be interesting to see if Rectin continues to explore tire development, perhaps even delving into the realm of mixing rubber and sulfur to create truly high-performance tires.

In conclusion, the world of RC racing on YouTube is a place of fierce competition and constant innovation. Michael Rectin’s foray into 3D printed tires is just one example of the ingenuity and determination that drives the community. While there are still limitations to overcome, his tire experiments have undoubtedly sparked interest and opened up new possibilities in the world of RC racing.
