I thought of that while typing, but I do not know enough about stereo lithorarphy and those new 3D printers to know if that material is strong/rigid enough to hold glass in place or even plexi-glass.
Even a hood with cool louvers/intakes, belly pans, .............. endless

Its a wonderful tool for reverse engineering an item. What it does is give you data to create an accurate representation of the original part. VERY VERY nice, as it takes forever to manually get geometry correct for lots of things. (Jerry is fighting this with the fenderliners!)
But, cost does come to play if you want to really recreate an original piece. The scanner gives you a 3d file, but it needs to be redrawn to be usable Machine data. But.. then comes drawing up a mold of the piece you want to produce (for plastic parts anyhow).. If the piece is injection molded, the cost of creating molds is cost prohibitive I'd think. 10-20k? for aluminum mold halves for fenderliners? Other molds might be cheaper, depending on the the part is created (vacuum forming mold or possibly a simple blow mold). But, we're still talking hundreds to thousands of dollars to have someone convert the scanned 3d file into a usable machinable part file. More money for the CAD person to create a mold from the part file. More money to have a mold shop create the part... and on and on. It CAN be done, and the technology is absolutely amazing. But there is quite a bit of cost involved that all add up.

The technology for converting is moving very, very quickly.
But I'm from Missouri on that. Wanna see it converted to real parts!
Big platen molds are always expensive.
This is front end, supposedly cutting design time dramatically.
It will be interesting to see it develop. I'd like to see the grill parts be scanned, smoothed, and sent across town digitally for cutting at our local shop and am told that's done everyday with this gear, with auxillary input from a 3d designer.
Just in measuring capability alone its incredible.
Imagine a drive-thru PPI, scanning just parts of panels, looking for hidden bodywork by comparing against some approximate standard (or a definitive standard if available).
That type of QA comparitive measurement function is highly developed already.

I would model the entire exterior of a 928 for $10K, w/3D scan data. $15-20K from scratch.
Someone mentioned headlight buckets. A couple hundred $. No scan req'd.
You're right though, it can get pricey quick.

These are usually finished to an even higher level by our models team and can be used as functional plastic parts or even painted to simulate finished products. The material we use for the SLA's is Accura 60 which is designed to simulate the properties and appearance of polycarbonate; in its cured state it has a tensile strength of up to 68 MPa with a flexural modulus of up to 3000 MPA and a shore hardness of 86. In comparison to FDM, SLA can provide a far superior surface finish and strength straight from the machine with layer thicknesses as low as 0.05mm on high resolution.

and in metal, that is functional. Should be good for a lot of parts except structural items.
No reason why we all can't have GTS rear quarters now and sink the GTS market.

Def. not A$100's of K's. More like some K's. As an example, I could model the fender liner for about $1K (at my current billable rate), if I had 3D scan data to work from. Double that if from scratch.

Our shop is about the same for the cadwork.
