Just for curiosity: which section of the EULA allows us to make renders, display our renders, print our renders and even sell our renders?
And which section does limit this to 2D-rendering and printing, and forbid 3D (4D 5D etc) rendering and printing?

My opinion:
The only thing I'm not allowed to do with content is to ship out (portions of) 3D meshes (and 2D textures) that contain (in the literal sense) licenced content. So there might be an issue with shipping stuff to a 3D printing service, like there is an issue with sending Poser scenes to a Poser Render Service if such might exist.
But I don't see an issue when 3D printing by myself, and don't see an issue when I render the scene into a JPG and send that out for printing service (as the JPG cannot be re-engineered into the 3D mesh), and likewise I don't see an issue when some 3D-rendering proces should exist (run at home) that turns the 3D scene into a 3D-print file in such a way that the originating mesh cannot be re-engineered. Then such a print file could be send out to a service bureau.

Perhaps I'm wrong, but then... prove me so by showing the relevant sections.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
