Export file to the 3D printer

Dear talented designers,

I am working on a project to develop 3D printing of Voronoi seeds. Using Rhino, 3D Voronoi designs are the main part of the project.
The STL file cannot be printed because the exported design is SURFACE.
Could someone help me with how I can change it to be SOLID to be printable?

Thank you in advance.


you can send me the file, i’ll have a look.
