Mad Manor of Astabar - Moon Skulls

No

0.1mm

Here's how I printed it:
Print surface: AnyCubic Ultrabase, heated to 80C for the whole print.

Filament: 3D Solutech Natural-color 1.75mm PLA

Extrusion temp: 220C first layer, 210C for the rest

Slicer: Simplify3D

Infill: 5%, fast-honeycomb

Cooling: 0% first layer, 80% at layer 2 and above

Supports x-distance: 0.2mm

Supports y-spacing: 1 layer above, 1 layer below

I was a little amazed that it worked okay with only 5% infill, but I'd recommend going with more - the bottom/internal edges of the symbols would really benefit from some infill to rest upon. I had a couple small gaps within the symbols due to lack of internal support (ie: infill). I printed all 8x skulls at once, as a single process (ie: layer-by-layer, not model-by-model), and it took about 14 hours start to finish. So, estimate about 2 hours per skull.

Support came away without too much trouble, but the teeth were kinda hit-or-miss. I lost a lot of teeth while removing the support. That being said, I don't really care - it just looks the skulls look less obviously-identical. Each one's missing a different random combination of teeth.

Aside: I've found that 3D Solutech filaments tolerate way higher temps than you'd expect of PLA. Most notably, at anything less than 70C, the PLA wouldn't stick to the Ultrabase at all. At 80C it sticks like glue, and completely releases itself as the plate cools to ~30C.
