Some scientists from the ICTP (International Centre for Theoretical Physics) published an open book about 3d printing, titled Low-cost 3d printing for science, education and sustainable development.
The book covers pratical issues (printer models, use of OpenSCAD and Slic3r) but also investigates the application of 3d printing in fields like science (including an experience from CERN), education and sustainable development.
A great job that is definitely worth a read!
