Those layered parts just need an acetone vapor treatment (see youtube vid) and it will be close to OEM usable!

Still Extruding: Vapor Treating ABS 3D Printed Parts

With these 3D printers coming down in price (about $500) like this one:

 you can probably print out a whole car for about $250 in plastic (about a 500 pound  plastic body)!  Even the filament (about $50/two pound roll) can be greatly averted by making your own for about $5/ two pound roll like this:

You can download the PDF plans for free at that site!

The whole car would be under $1000!  I would guess it would take 1 to 3 months to get it done (using these small machines (10 inch by 10 inch by 8 inch) or making bigger travel arms and heat plates using the supplied nozzle/controllers - to speed up the process) - mostly just supervising the machine as it does all the work!  Afterwards, just brush/spray/vapor treat the car with acetone and you would have a smooth shiny car body that you could pull molds from or even use as is - coating it with paints/vinyl wrap/chrome wrap (to reflect high heats)/ or even a coat of resin or gel coat!  All for under $1000 - ANY CAR, ANY MOLD!  That beats the cost of any fiberglass body!

All this being said, I wonder if the other type of 3D printers might not be the real future - the ones that scan a UV light over liquid plastic layer by layer - the part "magically" apears to rise from the liquid like something out of Star Trek, check it out:

Update

After waiting 30 days for my Cubex to arrive, I received an email from them telling me that it'd be another 30 days for delivery.  This was the last straw so I cancelled my order and received a full refund. 

I ended up finding a smaller Cube printer for about half the money in Dayton Ohio so I drove down and picked it up.  The quality is less than "finish ready" and the printer is limited on options for tweaking the printing output.  The materials are expensive and the Cube software is proprietary to the printer.  My advice, wait until this really begins to explode (about this time next year) and save your money.  I've decided to use this first printer as a learning experience (little spent and a lot learned) and save up for a larger multi-head unit next year.  The quality of the print is determined by the nozzle size and the nozzle size can affect the speed that the printer can run at. 

I tried printing the Reventon fuel assembly and it was estimated to take over 20 hours and would've used about $40 in Cube materials.  I printed out about half of it and canceled the job to avoid material waste. 

All of the ABS supports (break away) left the part very rough and you can clearly see the layers that make up the part which would not be acceptable to most members here.  The multi-head units can print separate support materials (and even different colors) that can be dissolved away and this wouldn't leave the rough edges from the break away supports but you'll still have texture from the layers.

As far as 3D scanning is concerned, I did a lot of research on this before spending any money and I've been told by several trusted sources that this is still a very time consuming process that is far from easy or perfect.  What they don't show you is all the steps involved in scanning then healing and converting into a point cloud before you can do anything with it.  There will be a lot of improvements in this area as 3D printing matures as they compliment one another in the area of reverse engineering and replication.

Just my 2 cents!   ::tongue

 Someone at the MM forum already posted this link.  The printing resolution is lower than that of CubeX and the printing quality is not yet proven. But I agree that prices of all 3d printers will go down if Chinese start to flood the market.

PayPal with my checking account as my funding source.  Not a big deal, I've looked at the other 3D printers and they all seem to have delivery times of around 3 - 4 weeks.  There are some "open source" versions on EBay, but I've been reading about the benefits of this Cube X printer and I think it's worth the wait (it's just going to drive me nuts!).  This will give you guys plenty of time to get your 3D drawings lined up so I can start printing for you in about 45 - 60 days.   ::tongue

I have a set of folding LP640 side mirrors that I think I can print in three pieces and bond two of them together.  The third piece is the base that is modified to fit a G28 door.  Anyone interested in a nice "finished" set of LP640 folding mirrors for the G28?  I'm also going to try printing some headlight brows with one piece hinges on the bases, a dome / courtesy light base for a roadster and the many other little hard to get and expensive OEM trim parts.
