Ivory Carving (Bas Relief)

A 3D printable replica of a carving done in ivory. Created from a photograph (original photo is included in the files) as a reverse lithophane (the whitest areas are the thickest).

There are two separate models - the base (Bas_Relief_Base.stl - a black rectangle) and the carving (Bas_Relief.stl). I printed the base first (of course) with a 0.25 layer height (including the first layer) to get a 1mm platform (four layers). I then changed to white filament and printed the carving with a 0.1mm layer height (first layer also 0.1mm), offsetting it 1mm above the print bed before slicing so it gets printed on top of the black base.

I modified my slicer (S3D) ending script of the Base to leave the bed heated during the filament change and made sure there were no 'additions' (skirt, brim, or raft) when printing the carving. I also used 6 top and 6 bottom layers (so no infill is used) and zero outline/perimeters shells (walls) for the carving.

The resulting print is 170mm x 140mm x 2mm.
