Interesting. If those pics there are of the actual final product, that doesn't look bad at all!

Maybe it's a hair too long to do as a one piece shell, so he made a convenient break to do it in two pieces?
It looks good!

Those are most likely computer renderings of the shell. I have designed and printed some detail parts for a project that I am working on and they did not look as clean as the renderings

@ DHilchie Welcome aboard!

Printed parts are not even close to the renderings.

true enough. wonder if it would be easier to sand and clean up with the shell in two pieces? not a loco that interests me, out of my era. the designer does mostly australian narrow gauge stuff so i assume this was a one off request.

i received two test versions of aussie hoppers done via i-materialise (one grey, one white) and they were considerably better than shapeways.

Thanks ConducTTor.

Is there an existing thread on 3D printing TT scale models? I have some pictures of a HO project that I am working on that is using some 3D printed parts from Shapeways, but I don't want to hijack some one else's thread.

OK, I need to put some more eyes on this!
Check out these two pics-

http://trainiax.net/drawings/ge/geb39-8.gif

Now it looks to me like the only big difference in the difference between the "C" and "B" is in the cabinet behind the cab- note the extra space grilles on the "C", I'm wondering if you did careful surgery would yield a B39-8? From what I've found out so far a 9 'wheelbase truck is needed, so sideframes would be the hurdle.
Any thoughts?

I find a B38-9 also better. But we need other pictures or plans. Some of the "B" have behind the cab, at the left side, a higher walkway:

And some not:

The tank is shorter than "C" and perhaps is the platform at the end longer. I think, the modification at the data is easier as at the model.
