3D Printing Hand Book

I bought this :

even though I operate a 3D Printing service and feel I have a good handle on desktop 3D Printing I'd bet for the 30.00 I'll learn something from it. Maybe not? Will post what I think about it after I receive it and read it. I would imagine, regardless of how experienced or not experienced you are, it may be worth a read. Maybe a good resource for someone you know who is thinking about getting into it?
