Vincent van Gogh's Starry Night Lithophane 3d μοντέλο

With FDM type printers I have the best results by printing on a side (upright) to benefit from the layer resolution, also PLA is better because of less warping (or use some discs for larger surface). The one in the picture was printed upright in white PLA (0.15 mm layers) on a PP3DP Up! Plus. It's best to use opaque material like white or yellow, ABS is possible but will warp more because of the thin structure.
