Those of you modeling in Sn3 know that the number of unique figures are limited. Artista, Aspen, Railmaster and PBL have all offered figures with only Aspen offering new people recently.
There is a real opportunity to make advantages of 3d printing here. A couple months ago I ordered two figures off of Shapeways. Now they are painted.
Unique poses are a plus. These particular figures are okay, but lack the detailed faces and clothes Aspen offers. I had to use paint to add some detail. More people are coming from a different Shapeways store.
ModelU in the UK are doing 3D scans and prints of railroad figures that are quite amazing. S scale is an option in the print. The downsides are many look more UK than US and the cost. But if you've the budget and are looking for detail...
