I initially printed this in black, flat on the build table, .1mm layers to try for as much detail as I could get. Then it occurred to me that if I tilted it up to about 45 degrees, the printer would generate much of the face detail with horizontal motion instead of layer deposition. True, it would require a LOT of support, but most of that was on the back face and easily removed. So I experimented, and found that 39 degrees did a pretty good job of keeping extra support from being added around the edges. I printed the tilted version in purple. Here are some comparison photos of the black (flat, .1mm layer height) and purple (tilted, .2mm layer height).
