I'm not a fan of Shapeways....purely on the basis that the way I develop models (initial design...print...modify design....print...modify design, etc) would end up far too expensive and take way too long for me to keep up interest in what I'm doing. I like to develop the finished article....rather than the virtual design!!
Now I've really got to grips with how it can be set up, my printer can successfully printing 0.05mm layers with a 0.2mm nozzle. Once I've finished mass printing for The Bridge, I'll have to see what small items I can successfully produce.
