Lithophane
A lithophane is a thin 3D panel where an image is encoded as varying thickness. When backlit, the thinner areas let more light through, revealing the image. This creates a beautiful way to display photographs and artwork.

How to Use
- Import an image or select an existing image object
- Apply the Lithophane operation
- Adjust the resolution and dimensions
- Print the result in a light-colored material and place in front of a light source
Parameters
- Pixels Per mm - Resolution of the lithophane (default: 1.5, range: 0.5-3). Higher values capture more detail but create larger files
- Height - Maximum thickness of the lithophane panel (default: 2.5mm, range: 0.5-3mm)
- Width - Total width of the lithophane in pixels (default: 150)
- Invert - Reverse the light/dark mapping (default: on). Usually kept on for correct display when backlit
Tips
- Print in white or light-colored material for best results
- A height of 2-3mm works well for most lithophanes
- Higher Pixels Per mm captures more detail but increases print time and file size
- Mount the finished print in a frame with LED backlighting for best visibility
- Portrait photos with good contrast work particularly well
