This is a 3D scan of a pumpkin with a face. It is a demo model from the LMI HDI Advance scanner.

I added 2 models: one is the original scan that is difficult to 3D print because of holes and high amount of data (FacePumpkinRaw.stl). The other has been reduced, oriented and made solid for easier 3D printing (FacePumpkinSolid.stl). This was done with MeshMixer, download it for free at http://www.meshmixer.com.
In MeshMixer there is the ''Make Solid'' option, basically a model will get digitally ''shrinkwrapped'' to create a new solid model.
