The 3D printing services will have Design Guides for each material offered. The guides show minimum wall thickness, minimum hole diameters, minimum clearance between two parts of a model, etc.

An example is here:

Thanks a lot Ed! As far as I see the detail limits in some materials reach even some 0.25 mm thicknesses. This means that there is a lot of freedom to do highly detailed modeling. Of course, there is the problem of polishing in the cases of too complex details. But, anyway, this is something that can be dealt with a careful planning in design.

Beautifully done! Wow.

Fantastic work!

Thanks Vegasguitars! I am following the discussion going on in your guitars thread! So many things to learn there! : - )

Now that I did see your message it is time to put here another ring making try... working in Moi on simple shaped rings, with smoothly flowing belts and motifs on them, is really a joy! Below there is an experimentation with translucent materials too. Wish to hear opinions from people here... both about the aesthetic side of the results and the technical possibilities of producing them with materials of actual life. Because it is easy to depict them with such materials in digital renderings but I am not so sure if it is possible to produce them in real life too. : - )))
