A 3D-printed machine teaches how to braid.
Have you ever been captivated by the mesmerizing dance of intricately designed industrial machines? Well, there’s something truly enchanting about watching braiding machines in action. Picture spools of thread or wire gracefully intertwine with each other, performing an endless ballet that produces a flawless braid. It’s almost like witnessing magic unfold before your eyes.

If you haven’t had the opportunity to witness this phenomenon, now is your chance to experience it with a remarkable twelve-spool braiding machine. What makes this machine even more fascinating is the ingenious building methods employed by its creator, [Fraens]. By utilizing 3D printing and laser-cut acrylic, the inner workings of this machine become easily comprehensible, even to those who may have never attempted manual braiding with more than three strands. Watching the video below is far more effective in understanding its operation than any attempt at verbal description. Essentially, each vertical supply spool travels along a continuous track surrounding a central point, guided by a series of six intermeshed gears. The spools weave together into a braid as they go around the carousel, passing underneath one another.
Numerous intricate details contribute to the functionality of this machine. Among them, the thread tensioning mechanism stands out. It consists of a lever arm and a spring-loaded axle located at the very centre of each spool. The gears responsible for forming the inside-outside tracks demonstrate clever design, as does the worm-gear-driven takeup reel and output tensioner. Additionally, the loading gate for the spool carriers is a thoughtful addition that enhances user convenience.
Watching a braiding machine at work is truly a captivating experience. Whether you’re enthralled by the artistry of engineering or simply curious about the mechanics behind it, these machines never fail to inspire awe. So, sit back, relax, and allow yourself to be enchanted by the mesmerizing ballet of the twelve-spool braiding machine.
