ArchiCAD matter

Hi! I'm an architecture student and I enjoy most working with ArchiCAD program. Last time I got more interested in 3D printing. For this purpose I was modeling in Rhino. Nevertheless I would love that, if there would be some possibility for printing stuff modelled in ArchiCAD. Did some of you ever heard about some way to do it? What programs should I use, to convert something from ArchiCAD file on printable file? Maybe you know, what is happening in 3D printing world and when could it be easily to accomplished? I would be thankful for all thoughts and discussion! :)
