SummaryNot a serious offering for a new royal birth souvenir, but a quick technical challenge to 3d print a Lithophane image via desk top 3D printing. https://www.youtube.com/watch?v=qZRzFZ9A7YI Interestingly, this technique of creating an image by varying the thickness of material so when backlit produces a photographic representation was popular when the new princesses, great, great, great grandmother was on the throne. Now created using a modern day technology. Came out pretty well! Interest on the internet as well: http://3dprint.com/63528/royal-baby-princess-charlotte/ Enjoy!
