With all this talking about recasting special models it came to my attention something truly different there is some companies that offers 3D printing here is an excerpt from roundstonedigital.com about 3d printing technology
WHAT IS 3D PRINTING?
Three-dimensional printing technology is used to build physical models from sketches, blueprints, 3D scans, CAD Files and many other formats. Using a computer and proper software, a 3D mesh is created to represent the object to be printed. This mesh data is then sent as many thin horizontal slices to the printer, which interprets the data and joins together liquid and powder materials to form complex parts layer by layer. Three-dimensional printing is the least expensive rapid prototyping process, which turns the 3D data into a physical model for conceptual evaluation. Where an ordinary printer lays down a single layer of ink on a single sheet of paper, these printers add the extra dimension by printing layer after layer in a vat of starch or plaster until you have a physical model identical that accurately reflects the original design. Parts with a wide variety of sizes, strengths, flexibility and surface finish can be produced with this method. Please visit our gallery for some examples.
My point is right now 3d printing machines are very, VERY expensive, but HP has announce a home model by the end of this year ($10,000 USD), they aspire to print from models to anything that needs replacement parts in your house, It's some kind of liquid plastic, can you believe the posibilities on developing your own models or replace parts to improve your own models not to mention increase the scale, if you own a 1/72 VF-22 with the proper scale you can reprint a largr version, I mean the posibilities are endless
