Now clearly the person who did this on CAD knows his stuff, but he seems to think that people should be prepared to shell out £50 or more for it!!
Of course if you have a view of a Teak coach as something very close to a rough cast platelayer's hut, then I'm sure you'll snap one up if you have more money than sense, but how about stopping for a time to assess what you are being offered. If you wanted a GNR saloon, with all its fine square cornered mouldings and beadings, you will be, MUST be, surely, woefully disappointed. OR, will you be a fashion victim and accept this lousy finish in the name of being down with da kids and up with modern techniques?
I don't care what they say about painting it with hi-build filler and sanding back, blah, blah...why the Hell SHOULD you? I'll tell you why. Because if you ever want a 3D printed item with anything like a surface finish that is acceptable, you'd better re-mortgage the house, for the only way 3D will ever give you the kind of surface finish that you would rightly expect on, say, a resin kit or even a white metal one, is if you shell out a massive wad of cash for the high resolution option.
To prove that I know exactly what CAN be done at a huge price, here is a picture of the Ryan PT-22 from Fisher Models and Patterns. I know Paul Fisher. He is a superb modelmaker, but he tried out a 3D print to get the incredibly fine detail on the cylinders of the Kinner 5 cylinder radial. He reckoned that he couldn't do that level of detail by hand, neither could I!
BUT...he described the cost of having JUST ONE of those cylinders 3D printed as "almost ruinously expensive". For a £150 kit it was worth the financial punt. He had just one 3D printed and then copied them as a stick of 5 which were cast in resin. Yes, you can have all the bolt heads that hold the cylinder head on, every tiny fin and even the word "KINNER" on one of those tiny rocker covers, but don't forget..."almost ruinously expensive".
Let's get real and stop believing all the crap shoved at us by the techie press. If you like your Gresley teaks looking like they were painted and then dipped in caster sugar from 15 paces, you go ahead and swallow all the garbage trotted out about 3D printing. If you want quality surface finishes, be prepared to put yer money where yer mouth is for at least the next 5 years and stop flogging rough cast crap until then...
