Say hello to TwoEarsTwoTeeth, a model I sculpted in ZBrush that I use to test printers. It can be printed on large printers like the CR10S or at a smaller size with SLA printers (Photon, Wanhao, Form2, etc.).
Because it has details, flat surfaces, large areas, need for localized supports and more, it's a great benchmark model.
Please don't use this model for commercial purposes. If you expose this print (photos, other), would you mind crediting "Polysculpt.com"? thanks :)
FDM Printing recommendations:
You will need supports for FDM printers on the mouth teeth areas like visible in the images. But except here, no need for support on other locations.
At least two outlines, three is better. Provide good results at 150 Microns. Infill is needed on some areas will grow from the inside part of the mesh (around the eyes) and it will support parts with a strong angle like at the tip of the ears. Variable infill should be ok.
Raft is up to you, but not mandatory.
SLA Printing recommendations:
Supports are obviously needed on the teeth, but based on the orientation, you may need them on other location. Never forget to check layers by layers in your slicer to see if you have some parts growing without supports.
Depending on the size, you may need to hollow the model, but be careful to add vents holes to avoid the suction cup effect.
