Using a 2D Scanner to Make 3D Things

Chuck Hellebuyck found a creative way to replicate model car raceway tracks by using a flatbed scanner to capture the profile of the track’s cross-section. By scanning the track’s profile and processing the image in Tinkercad, he was able to create a usable 3D model of the cross-section, which he then extruded to produce an accurate clone of the original track piece. This method of using a flatbed scanner for purposes beyond typical image scanning is not entirely new, as it’s also commonly used for tasks like scanning PCBs to capture mechanical details.

Hellebuyck’s project aimed to build a complex raceway for his grandkids, requiring many track pieces, including curved sections joined at various angles for cars to race downhill. After a successful test print of a small track section using Ninjaflex, he found a way to incorporate both flexible and rigid track sections to manage the curves. The use of Ninjaflex allowed for easy connection of rigid sections in curved areas, demonstrating the versatility of modern 3D printers, which can handle printing tall, thin structures vertically without significant issues.

Overall, this project showcases how combining 3D-printed custom parts with readily available components can achieve desired results efficiently. It highlights the potential of integrating simple scanning techniques with 3D modeling and printing to create customized solutions for various hobby projects.
