Most prototype machines have a work area of approx 12 x 12 x 12 inches but the joins are almost invisible and the joins are stronger than the part as I usually put in dowel points for alignment & strength and adhesive is used. I have made a paint mask for the International Lonestar model's hood that's pretty damn big all from CAD data. I have also done front fascia's of cars, the Hummer tool box, phoenix engine block as seen in previous pictures, done picadilly rails forearms for assault rifles,inventions, wind turbines for wind tunnel test, 3d art, medical prototypes etc....the list goes on.
