In ceramic tile manufacturing, creating colorful, thick glaze layers with intricate patterns is a challenge. Existing machines typically allow only a single color glaze or require very high-end inkjet printers that can’t handle thick materials. These machines are expensive, hard to maintain, and have strict material requirements—making them unsuitable for dusty, humid factory environments.
The Invention
This invention is a new type of digital printing machine designed specifically for spraying colored glaze slurry onto ceramic tiles. Unlike traditional machines, it can instantly mix and spray multiple colors, apply thick layers, and create 3D patterned effects—resulting in vibrant, polished tiles. It works using a system of modules with slurry tanks, controlled spray nozzles, and smart circuitry to precisely control the color and thickness of each spray.
What’s New
The breakthrough lies in the multi-channel nozzle system and its ability to blend different colored slurries instantly before spraying. This is achieved using a clever push-pin and electromagnet system that controls the flow from each tank in real time—something no existing machine does with such simplicity and flexibility. The design also tolerates coarser, thicker slurries, which previous digital machines could not.
Tangible Benefits
- Print vivid, multi-colored 3D glazes with just one device
- Works in tough factory conditions (dusty, humid)
- Low maintenance and production cost
- No need for ultra-refined materials
- Can replace multiple bulky machines with one compact solution
Broader Impact
This device could revolutionize ceramic and artificial stone manufacturing by making it easier and cheaper to create high-end decorative finishes. It reduces waste, simplifies production, and makes artistic tile designs more accessible—boosting both economic and environmental sustainability.
