After getting first prints of several of my designs I wanted to check, before offering them for sale, clients would be getting at least the same quality. So before putting them for sale I ordered a second print of several models.

Here is the result of my first attempt, back from Shapeways:
("Wagon2.jpg" in the "Freight wagon project" file, in case this link doesn't work.)
I'm reasonably pleased with it, but a lot of the fine detail has been lost, even in 'frosted ultra detail', which is Shapeways' best-quality plastic material.
My feeling at the moment is that the 3D printing technology may not be quite ready yet for serious modelling in 1/87 or 1/76 - at least at 'rivet level'.
Right now I'm working on a modern tram model which has far fewer small details and may give better results.
Thanks to all for the useful tips and advice!

890 DPI for FUD

removed by sanding or scraping. This is how one of my customers tackled
the process <http://www.lner.info/forums/viewtopic.php?f=3&t=6919>. I
saw the finished model at the weekend and the surface finish is
indistinguishable from an injection moulding.
