3D printing for model railroading?

by Thomas Beutel

Shapeways looks really interesting. According to Technology Review you upload a 3-D design to the website, and 10 days and $50-$100 later, you receive a polymer version of your design.

I can see this as really handy for creating masters for items that I want to replicate in urethane or plaster, such as bridge parts or passenger car sides. Cool!
