You can export Vasari models to stereolithography (STL) file format using the STL Export tool.
External Tools drop-down
STL Export. In the Export STL dialog, choose Binary or ASCII for the STL format. The graphics generated are based on the current view. If the current view is a floorplan, the result is 3D geometry based on the View Range setting. The geometry also respects the Visibility/Graphics and Hidden Element settings for the current view.
