Resin casting is severely size limited. Injection moulding and casting iron, BTW, require oversize machine tooling/lost wax blanks/sand moulding patterns etc. so that the finished parts will come out the proper size when cool.
Plastic and cast iron aren't so bad, but you should see the size of a toilet before the ceramic is fired! 8-o
CNC Milling and Stereo Lithography are definitely the way to go for this kind of thing.
Good point about the manual model-building method though, that's not too bad. But like in 2D graphics, it's a LOT easier to clean up a scan's pixel pancake in Illustrator than to scale it in manually. Point clouds in 3D are probably a similar deal at a CAD seat. [
