3D print for everyone

Where to go when I want to print something, what do I need and how much it costs (FabLaby, Shapeways, Trider, custom printing). 3D print for designers (bridge donkey - water) How to create data for 3D printing, what goes and what is possible, special materials (SW tools, know-how, new and new materials). 3D print for geeks (donkey bridge - air) I will build 3D printer how to do it. Why it is good to go or do it better (Arduino, stepper motors, types of constructions and their benefits, open source SW). 3D Print for Scientists (Robotic 3D Print, 3D Printing of Metal Materials for ESA)
