Breadboards have long been a staple for electronics enthusiasts and students alike. The name itself dates back to the era of vacuum tube circuits, when large components were often mounted on wooden boards—similar to how one might cut bread using screws and nails. As technology advanced and components became smaller, the name "breadboard" stuck, even though the physical form evolved.
Today’s breadboards are typically rectangular or square, featuring numerous small sockets that allow for solderless experimentation with electronic circuits. This design makes it easy to insert and remove components as needed, eliminating the need for soldering and saving time during assembly. It also allows for reuse of parts, making it ideal for prototyping, testing, and educational purposes.
Recently, Les Hall, an experienced electronics engineer, had a creative idea: what if we could 3D print breadboards to make them more versatile? He wanted to break away from the traditional flat shape and expand the possibilities of where and how breadboards could be used.
“I’ve worked with breadboards for 30 years—whether in school or at work. They’ve become a part of my life,†Les said excitedly. “I developed a method called ‘the neat freak technique’ for wiring, and now I’ve created a 3D-printed breadboard.â€
To those unfamiliar with the concept, this might sound a bit abstract. But for Les, it’s all about innovation. “The breadboards we know today are flat and somewhat boring. Even when connected together, they remain square. With 3D printing, we can create breadboards in any shape or size—like the body of an airplane or a car, or tailor them to specific electronic needs.â€
Combining 3D printing with conductive materials like graphene opens up new frontiers in electronics. “At a basic level, 3D-printed breadboards can have holes of any size or spacing, accommodating different components such as audio jacks or switches. While this may seem simple, it unlocks endless possibilities,†he added.
