I got to watch one of the Form1's working. (along with 2 laser cutters) He was using it for S and O scale parts, not really ready for HO or smaller yet. Someone else who designed 3D HOn30 trucks in Shapeways FUD had it printed with a Form1 and it was not good looking at all. Whereas the Shapeways trucks came out very nice.
Probably just another case of waiting till it works for smaller scales.
There is a Yahoo group for 3D "Steam Freight Car Printing" aka 3DSTFC and there is a guy named Bill Lane (He's an SPF) that bought a Forms 1+ last year and has been using it for S and O scale items. But for the most part he's printing no detail items like motor mounts, tender floors, etc. He has published some information on his web site
http://www.lanestrains.com/Do you know which resin he was using? Formslab has two resins for 25 micron layers, the grey which is like the Shapeways FUD and the black which would be the FXD equivalent.
There are other colors which range from 200 to 50 micron targets.
i'm assuming 'laser spot size' is what we'd call resolution and imo that needs to be sub-100 microns for n scale.

More or less. Think of it as layers either 25, 50, 100 or 200 microns thick of 140 micron diameter dots. Depending on orientation it could be okay for N-Scale or not. But no doubt a smaller spot would be desirable if the speed was suitable.
