The printed parts are indeed quite massive.I'm not sure if you have any experience regarding 3d printing, but the surface quality of 3d prints is still pretty awful. At least if you want it done in a comparably cheap (I would estimate ~250€ for the printing alone if the parts stay as solid as they look) FDM process. The surface will improve if you upgrade to something like an ObjetEden or go with an SLS/SLM process, but the costs will balloon out of control quickly.To get a starting point you can upload the 3d model of one of the parts to something like shapeways.com to get a quote on the estimated price.With parts that big you'll either have to do some sort of manual surface conditioning like sanding and varnishing or live with a surface that really only looks good in pictures with crushed contrasts (to hide the surface structure).
