Hi guys,
Apologies on butting in on your group, but I thought you guys might be interested in a free eBook?
It's called "The Family guide to 3D Printing", you can download it here: http://makerclub.org/family-guide-3d-printing-e-book/
It's in English, and is a quick, easy, colourful overview of 3D Printing and it's uses in education. Experienced pros could find it interesting, but it would be a great way to introduce 3D printing to the uninitiated.
I hope it's helpful/interesting to you guys :) x
