I've thought about resin casting myself, but never gone any farther than thinking. And now I know why the Verlinden resin stuff was so expensive... 3D printing would probably be the better way to go cost wise over the long haul. Molds degrade and must be re-made so there is an ongoing cost that a printer does not have. I'm sure there are some printer maintenance costs though. My problem is getting my projects into digital files because I don't have or know how to use a CAD program. Plus 3D printed parts are still usually rough from the printing process and require some smoothing. As printing matures I think it will mostly replace resin molding. I did say mostly...
