A lithophane is a three-dimensional image that becomes visible when illuminated from behind. To produce a lithophane using 3D printing, one typically starts with a grayscale image, where lighter areas represent more transparency.

Specialized software is then employed to convert this image into a three-dimensional model, adjusting the thickness of the material based on the varying shades in the image. Once the 3D model is ready, it is sent to a 3D printer, which builds up the layers of the lithophane using a translucent material.

The resulting print, when backlit, reveals the intricate details of the image, creating a captivating interplay of light and shadow. This artistic application of 3D printing showcases the technology’s ability to transform digital images into tangible, visually striking objects.
