Anyone used 3-D Printing to reproduce parts?

Even though I'm turning 60 this month, I like to keep up with technology (It's also my business). I was looking at a thread somewhere about the plastic cups that cradle the rear seat bar latch in a 65 Barracuda.....Mine are broken to pieces and brittle. No real chance to find new or repro parts. I was thinking that if someone had a good example, then we could have the part scanned and I could get the part reproduced using a 3D printer! I would love to try it out if I could find a good part that could be scanned and the digital file sent to me to try and reproduce. This technology could be a lifesaver for lots of hard to find smaller parts! What do you think?
