There are several companies that will "print" models for you from your design.   Some model railroaders are already doing this.  A member of the Nn3 Group on Yahoo has had some Nn3 gondolas made by Shapeways  http://www.shapeways.com/

I tried to sell my two cents worth, but no one would give me a plug nickel for it.

I don't have a leg to stand on.

We have one of these gizmos at work.  They're kind of clever -- they produce a resin model.  It's not for the model railroader.

Printer costs upwards of $25K (maybe cheaper options), resin costs about $1500 per refill, and they don't last long.

Given that one of their "real world" applications is architectural prototyping...well I think you know where I'm going with this.

The "copier" (as some engineers call them), which one of our high schools has in it's engineering magnet program, cost about $ 24,000.00 at the time of purchase. They use a (phenolic?) dry powder or pellet plastic material and are usually integrated with a CAD-CAM system. I have often thought of drawing some building components at full-sized HO scale and then seeing if I can get them made to order, so to speak. But don't think you are going to scan a brass locomotive and get an operable one right out of the oven, so to speak.... but the thought is enticing, isn't it????

The technique does have applications for modeling non-functioning items, though, such as vehicles, figures, and locomotive details. The technique (called "rapid prototyping" or RP) allows one-piece modeling of parts that previously could be molded only separately, such as a tank truck with a stand-off end ladder. There was an article about modeling with RP in the November 2007 issue of Fine Scale Modeler, and we're looking at a similar article for an upcoming issue of Model Railroader.

First, price the `printer.'

Second, note that the working crescent wrench has all parts made of the same material.

Third, this Las Vegas resident will wager $$$$ that the `printed' wrench is nowhere near as strong as a real, drop-forged, hardened steel Crescent adjustable wrench.

There's a lot more to function than simple form.

Today a friend of mine sent me an article about three-dimensional object making using a printer...

It was pretty interesting; in the article, they "produced" an adjustable (crescent) wrench-in a printer!!This puppy had all the moving parts, etc-bottom line:  It was functional and useable-and an exact replication!!!  HOT DOG!!!

Now, lessee............Take an O-scale brass Pacific, set it to down-scale to N, pop it in the ol' printer, press a few buttons, and.....
