3D Printing Suggested Thickness for 3D printing sculpts?

I don't know much about 3D printing, so take this for what it is.

Do you have your own printer? If so, why not print out a few small sample shapes in different thicknesses? That way you can test strength and weight and get a feel for the material.

 

You want it to be 10mm - ish thick in all areas for stability... it kind of depends on the type of printer and whether you're using a resin printer or filament printer. When I hollow my prints I leave the nose and ears, for example, un-hollowed but hollow out most of the head. A filament printer with that brittle abs plastic will actually hollow for you and there will be supports inside. A resin printer will print whatever you put in the program (so solid if you send in solid) but beware if you if you are printing something that's hollow with a resin printer, make sure you have at least two separate exit holes or your print may have weird warping.

I've had both filament printers and currently have a resin printer so feel free to ask more questions if this is confusing. I've also sent many things to Shapeways so I can help answer questions on how to hollow for them without getting the piece too thin for their printing standards.

Unfortunately I'm much more familiar with ZBrush than Blender but I can try and help

 

I’m so happy I could help at all! Can’t wait to see your prints
