3D printing of solid walled objects costs much more than say, filigree, mesh or screen forms. Many CAD programs, such as Rhino, display files as wireframes and mesh by default and can be rendered to look solid. Please excuse my still limited knowledge here.

Can anyone help me to print objects that are actually mesh or equivalent objects? For instance, say I have created a sphere using Moi, or Rhino. I would like to convert said 3D sphere file so that it will actually print a mesh walled sphere.

Actually, I have more complex files already made (picture frames, stylized block etc.) but want to convert the solid planes of these objects to filigree, mesh, wire or other "open architecture" so that they will print same. Hope this makes sense.

Thanks.
