In simple terms, a 3D printed lithophane is a unique type of 3D print that uses the thickness of the material to create a visual effect. The image or design is embedded in the material in such a way that it becomes visible when light shines through it.

Imagine a flat, thin piece of material with varying thicknesses. The thickness corresponds to different shades in an image or design. When you shine light through this material from behind, the varying thicknesses cause some areas to be more translucent and others more opaque. As a result, the image or design appears with different levels of brightness, creating a visually striking effect.

People often use 3D printing technology to create these lithophanes because it allows for precise control over the thickness of the material. The result is a captivating and detailed image that seems to magically appear when illuminated from behind. Lithophanes are popular for creating personalized gifts, decorations, or artistic pieces that come to life when backlit.
