What is a lithophane?
A lithophane is a thin 3D print where dark and light areas are created by different material thicknesses. When light shines from behind, the image becomes visible.
Make better lithophanes from photos.
A lithophane uses thickness and light to reveal an image. Upload a photo, adjust the subject, and download an STL file for 3D printing.

Photos that work best
Choose a clear subject
Portraits, pets, and simple motifs work best when the main subject is easy to read.
Use good contrast
Photos with a clear difference between light and shadow usually produce a more readable result.
Avoid busy backgrounds
Calm backgrounds make it easier for the subject details to stand out when the lithophane is lit.
Think about light and print orientation
A lithophane is meant to be viewed with light behind it. Material, layer height, thickness, and print orientation all affect how clearly the image appears.
