Printed on a Replicator 2 standing on edge The original image is 2048x1536 pixels, the Lithophane tool was set to
Max Size (MM): 199, Thickness (MM): 10, Border (MM): 1.6, Thinnest layer (MM): 0.8, Vectors per Pixel: 5, Base/Stand depth: 0
The printer was set to 10 perimeters (i.e. never fill)
There was very little stringing, the image shows the output without any cleanup.
I didn't use any raft (I assume this is the "backing" you refer to)
Hope that helps :)
