To recover the seals’ three-dimensional form, Margaret Root provided the UM3D lab with an outline of the imprints in Adobe Illustrator. From the outline, Stephanie O’Malley of the 3D lab added varying amounts of grey to generate a depth map, where the darkest areas were the most inset and the lightest areas were the most protruding. With a depth map in place she was then able to inset areas on a cylindrical mesh in Zbrush to re-create what the cylinder seal (the example seal is the “queen’s seal” ) would have looked like. Shawn O’Grady of the 3D lab has printed one of these seals already.
The lab has since obtained the new Projet 3D printer, and plans are now underway to eventually print one of these on the Projet since it has a much higher print resolution and these seals are typically quite small.
