Why couldn't a person still scratch build if they wanted? Imagine this. You want to make that Bugatti. You could buy a die cast one and resin cast it. The last time I checked, it cost me about $50 to do this with a promo and yes, I had to learn how to do it. Instead you take a webcam (demo on utube)or iPhone and take a 3D picture scan of what you want to make. This will cost you $.99 using the iPhone. Then you put the picture into 3d software on you computer, turn on the 3d printer and go have a cup of coffee.

Blender 3D software is very good and open source plus cross platform. With the open source community involved in the development of these printers, it won't take long for progress. They are now printing with metal and making circuit boards complete with solder. To learn about open source go to: http://en.wikipedia.org/wiki/Open_source.
