3d printing lithophanes

“A lithophane (French: lithophanie) is an etched or molded artwork in thin very translucent porcelain that can only be seen clearly when back lit with a light source.”

3D-printed plastic works fine, too. There is an excellent post on the RepRapPro blog describing the whole process from start to finish. This was something we just had to try ourselves, of course.

Sonic lithophane

There are a number of steps to follow but it is not particularly difficult. Images with high contrast work best; cartoons and woodcuts are ideal. This Sonic the Hedgehog lithophane was printed in PLA with a 0.35 mm nozzle and a layer height of 0.1 mm (base layer 0.26 mm).
