In order to display a flat lithophane you need to mount a light source at it's back, which invlves a lot of work. This process is much easier for a lithophane that is wrapped around a plastic pipe. When you have a CNC milling machine with a rotation axis this is an easy process. The video shows how to create toolpaths for the lithophane image, for the engraved text below and for the base of the lamp-shade. For all these steps the actual milling process is shown as well, plus of course the final result.
