You can do that now by using silicon rubber moulds and resin.......some have been doing it for years. Quicker.
It would probably take 9 hours to print a coach (probably more). They are quite slow and it would be cheaper to buy a coach as the plastic type on a reel or ABS reel cost a bomb....and you have to be able to CAD in 3D
Printers? - - new kid on the block!!
Probably would take a while. This depends of course on the resolution you have your printer set too. Printing an entire coach in one go would be a task. Best results would be gained by breaking it down into components then printing it out as 2 ends, 2 sides, detail parts etc...
This little scanner would be the beez kneez though for things like figures, station accessories etc. The price will drop, just give it some time for the glitches to be worked out...
I have taken a keen interest in 3D printing, even consulted an "expert" who 3D prints custom model aero components. With prices dropping and quality and resolution improving by the day I will soon be making the purchase.... "Flat" items to draw up in 3D are not to hard, its just getting used to working in 3D. Compound curves eg roof ends, are another thing. There is software available too that converts a large number of photos into a 3D file. But when I say "large" I mean in the order of 1000's for say the front of a diesel loco....
Look at this 3D printer won't do a coach as its too small unless you break down your components to a size that will fit. It Uses "Makerbot" components which seem to be available easily especially the nozzles...
