This type of technology has actually been in existence for many years, and certainly it advances every year. In case you did not know this...TGF has similar equipment right in their facility. Many vehicle prototype parts are first made with similar 3D modeler equipment. In the case of prototype parts, the part is modeled directly from the design print. Either way (scan or design print) the 3D modeler machine creates an actual duplicate of the part.You probably didn't know that many show / concept cars you see for the first time at auto shows have many parts made exactly this way. If it is not a running concept car, they normally just paint or cover the part with fabric and while you think you are looking at actual parts, it is really these plastic modeled pieces.
Since TGF builds concept cars for many OEM manufacturers, they have a few of these machines that are in operation all day long. (As you may know, TGF did the first Prowler concept car for Chrysler)
I have seen the machine in operation at TGF and another facility and it is truly amazing to see a part taking shape right before your eyes, and then to take it and hold it in your hand. Yeah maybe one day we will have to make some replacement Prowler parts using this method.
