Saw some of this at the London Model Engineer in January. They were making some intricate Platform canopy supports for an 0 gauge model railway, they were rather impressive.
Also has the advantage once you have put the CAD in it can be scaled to produce the component to any required scale. (whilst we were watching the demo ewith a half a dozen key strokes they cot the printer to turn out the exact same item in 00, and the 1 gauge.)

certainly is........like I said initially ,printer costs will come down , a cost of $2 per cc , wonder how that equates to injection/resin etc? any one know?

I pay about £40 for 2kg of resin, not sure how many cc's that is! Then you have rubber to make a mould. For making a one off or master the reprap would be amazing if you can make the 3d drawings necessary (I'm no computer expert!) and would be more accurate and cheaper than having a master made by a pro model maker.

Of course - you need the 3D drawings first. I heard a story that a country who ordered Hawks wanted the 3-D drawings of the exterior to do some wind tunnel tests, and was told "No problem - they cost the same as another full-size plane". Rather overshadows the cost of the resin and 3-D printer ;D

$70 is very very cheap for a commercial service. A 1:72 scale model in the UK would probably cost £500 to have 3D printed commercially.
I know, I've had some small parts made and they cost £180 to have done well. Yes, there are cheaper services, but quality suffers.
The 3D model won't come cheap either. Even entry level commercial software costs £500 - £900; and then there's the time needed to lean how to use it.
But these will drop in time.

The open source I posted the link to has a link to an open source 3d software package too en.wikipedia.org/wiki/Blender_(software) This may not be as 'professional' as some but I'm sure it would give better results than most (including me) could scratchbuild as one off model parts.

I had a dabble at doing 3D printing whilst doing a course for using a 3D CAD (Computer Aided Design) program. Whilst impressive, it was quite a slow process and the CNC machine to do it was very expensive. Unfortunately, the use of 3D CAD will be necessary to use this modelling technique as well as the machinery. To buy any of the most widely used 3D CAD programs is prohibitive as they are industry standard. We are talking of well over a grand or two for Solid Works, Pro Engineer, Solid Edge or Autodesk Inventor, the main players software. The 3D printing machine that I used whilst training, I was told, cost about £6K and it was a very small machine.
