ABSTRACT:
A system for volumetric digitization of three dimensional objects including apparatus for filling any cavities in a three dimensional object and volumes on the outside of the object with a generally opaque support material and solidifying the support material to a solid block having generally uniform hardness before digitizing is undertaken, apparatus for digitizing a first exposed surface of the object, apparatus operative following digitizing of the first exposed surface for removing a layer of predetermined thickness of the object to expose a second exposed surface and apparatus operative to digitize the second exposed surface of the object.
