That's pretty awesome. If you do a new vehicle, it would be good to study the actual vehicle so that the parts work, or move anyways, at that scale, they should. I have the 1/8th scale Jaguar XKE, like the one below, it's 90% finished. The suspension works, the Windows crank up by the windows crank, the wheels steer, hood flips up, and the engine detail is amazing. I had one new in the box, and sold it e months ago for $275. I needed the money. I had only paid $35 dollars for it 20 years ago. I still have the one left though, and that's enough. I grabbed these pics off of the web. Mine is Red. I had the same guy offered me $200 for the one I have almost finished. Monogram lost the molds when the factory caught fire, and the Fire Department sprayed the building down with saltwater, destroying the molds. They should have let it burn, the heat would have done nothing to the molds. What a loss. So many models that will never be able to be had again. It killed Monogram.
A model at 1/6 scale would be better served with detail, like working suspension. Make the right car, you could get a fortune for it! People are selling the programs too, though copyright issues will start popping up soon.
That's an awesome Hummer, what did you end up doing with it? Was it in a movie? First time I ever saw a resin/liquid/laser 3D printer was in 1983. it was classified, for rapid prototyping, and the software was proprietary. To be honest, I think these printers have taken too long to develop, they are too slow. The printers being used by the defense companies are decades ahead of anything we are seeing. What G.E. is using in house is almost Star Trekish.
