We read that it was possible to use a 3D Printer to make a lithophane from a photograph. A lithophane is an etched image that appears 3D when back lit and traditionally they were made by etching a design onto very thin porcelain. We wanted to make one using PLA plastic filament. 
So we used this photo of St Magnus Cathedral in #Orkney and ran it through some software to create a .stl file that could be sent to the 3D Printer.
It came out looking like this. Not bad but a bit rough looking. It looked as though it had missed a lot of the detail. Of course it was only a first attempt but we were a little bit disappointed...
...until we held it up to the light 😍
