I continue to research high detail 3D printing options and I came across another Objet printer that Shapeways may want to consider adding to their production capability, the Objet Eden500V: http://www.objet.com/3D-Printer/Objet_Eden500V/ It has 16 micron resolution in the z axis and - crucially - can use a gel instead of a wax as the support material, eliminating the surface roughness and artifacts we currently see with FUD. I would love to have access to this print capability, assuming it could be offered at a reasonable price. Worth considering when it comes time for Shapeways to upgrade their machines. P.S. - I am in no way affiliated with Objet, just a modeler looking for the best bang for the buck when it comes to high detail 3D printing.
