3D printing Clean Touch: keeps you away from bacteria

Do you ever get annoyed by the constant need to press buttons in public spaces—like elevators, doorbells, or ATMs—knowing they’re probably teeming with germs? If that’s something that frustrates you, then you’ll love Zach Friedli’s clever invention: “Clean Touch.” This innovative bacterial protection device was designed and developed over two years by Zach, and it’s a simple yet effective solution to keep your hands clean in high-touch environments. The product is essentially a 3D-printed plastic sheet with a round hole at the top, covered by a flexible antibacterial film. When you need to press a button, simply place your finger through the hole, creating a protective barrier between your skin and the surface. Once you’re done, just pull your finger out without touching anything contaminated. Afterward, wash your hands thoroughly with soap and water for optimal hygiene. Though it looks simple, the development process wasn’t easy. Zach started by manually sketching and modifying the design before working with an engineer to create a 3D model using SolidWorks. He then converted the model into an .STL file and sent it to WhiteClouds, a professional 3D printing service. The final product was printed on a Stratasys Connex 500 multi-material 3D printer, which allowed for both rigid and flexible materials to be used in one print. Zach shared that one of the biggest challenges was integrating two different types of materials into the prototype. But WhiteClouds made it possible, successfully printing both hard plastic and flexible film. “They were able to bring all my detailed designs to life,” he said. For Zach, 3D printing was a game-changer. It allowed him to quickly create functional prototypes, test them, and make adjustments rapidly. “I can make major changes every week, and it keeps the whole development process fast and smooth,” he explained. “Functional prototypes are essential during testing.” Another benefit of using WhiteClouds was the quality of the final product. “I wanted this to not only work well but also look good in photos, which is important for our Kickstarter campaign,” Zach added. Zach is currently running a Kickstarter campaign aiming to raise $50,000 to fund the development, testing, and manufacturing of the final “Clean Touch” product. Supporters can pre-order the device starting at just $12, making it an affordable and practical solution for everyday hygiene.
