The 3D printer at the library I work at was just named "Turing" after Alan Turing, so we printed this awesome Lithopane! Turned out perfect.
0.20mm layers, raft, no supports, 205 degrees on a Makerbot Replicator 5th gen
That is super cool!
I think either the nozzle needs to be a little closer to the bed, or the nozzle size may be wrong. Just my 2c....
