czhunter Hello @Ante80 ,
it is not easy to say - in general, Black High-definition should have the best surface quality.
On the other hand - it is least predictable, as the outcome is much set by how Shapeways engineer set up the prinitng supports - and I have no control over this.
FUD/FXD is "well knows classic" - with little bit worse surface quality (= more sanding) at the surface where wax support touches (in this case roof), but quite predictable. In reality, 3D print is usually never 2 times exactly the same.
czhunter Hello, thank you for your interest!
First: Yes, I'm planning IR4, IC4 and IC2 in N and TT (H0 would be very expansive and its easier and cheaper to mod Electrotren model) - should be done before Christmas.
Later I will do Oresundtog and Litra SA (4-peice ... maybe 8-piece as well).
About the undercarriage - I can't give you exact advice - I'm rather 3D modeler then train builder (I'm building TT railroad, but my models are bought or slightly modded).
Theoretically, IC3 has Jacobs bogies, so DB Talent/Talent2 could work ... but I don't know if you can fi it in - Denmark trains are always "closing" to the bottom (bottom is narrower then middle space) - that is not typical for trains in other countries.
czhunter Hello dice5
Now Litra SA/SE, then IC2 (I need to find some photo of roof details first - not so easy, IC2 is not well documented) and rescale all to TT scale.
Then Oresundtag ... and later maybe swedish X2000 ... but that is plan for next year.
