I'm having an issue with the solidify modifier. First off, all of my bodies are manifold so I've already been through that drill. However, every time I use the solidify modifier it adds thickness to the model but it doesn't "fill-in" the model. It seems to leave a void gap between the outer layer and the inner layer (see attached images). Can someone explain to me how I create a model that is "filled-in" and why it does this? Trying to 3D print an alien.

  • $\begingroup$ I think you have a misunderstanding on how the solidify modifier works. It basically takes your model, scales it in, and reverses the normals. So you would model the outside of a glass, and then the solidify modifier generates the inside. It doesn't fill it in with some sort of actual material, it just creates another surface to make it look solid. From my understanding, A piece of software for converting a 3D models into something that can be printed will make things solid. So if we where to go back to the cup example, the software would make the parts of the cup that were solidified solid. $\endgroup$ – TARDIS Maker Aug 25 '15 at 14:01
  • $\begingroup$ Oh that makes sense. So as long as the model is manifold the pre-printer editing software should fill in the bodies? $\endgroup$ – Rylan Hess Aug 25 '15 at 14:17

  • $\begingroup$ @catlover2 how do I upload an image in the comments? I'm new to the forum. Thanks in advance. $\endgroup$ – Rylan Hess Aug 25 '15 at 14:29
