Reading through this book, I was amazed at the amount of content that was in here, and most of the tutorials were great for someone new to 3D printing, but i'm willing to bet even some of the most experienced 3D printer people out there haven't tried all of the different things compiled in here.
If you are buying this book for printer reviews, you're much better off with the "Make: Ultimate Guide to 3D Printing 2014". It has more printers, and is more up-to-date, even though it was available (for me, anyways) before this book. As an example, this book reviews the Felix 1.0 printer from Felix Printers, where the new guide reviews the 2.0. (and the 3.0 is already shipping, so not sure why they take so long to test) This was the same with the cube printers, and the MakerBot Replicator 2 vs the 2x.
If you want to learn 3D modeling, this guide offers a lot of options and even walks you through making a pencil topper in TinkerCAD. There was a bunch of information about slicer as well, which was informative about 3D printing, but the found it odd that a guide for complete beginners didn't even mention that this was not needed for someone using a MakerBot Replicator 2.
Really enjoyed the scanning tutorial, but it was literally copied and pasted from the "Getting Started with Makerbot" book a year ago. The cleanup guide was actually stated in the first page that it was outdated and a new video was posted, but instead of updating the tutorial, it was the same one as in the old book. Also, it mentioned that Mac users have to use some type of Windows with ReconstructMe, and mentions nothing of the Skanect software, (released in January 2013) which is a decent Mac alternative. Again, something mentioned in the magazine that didn't make it in this book.
Finishing Techniques and Post-Processing
This was my favorite part of the book. It mentions things like how to do friction welding to put pieces together with just a rotary tool. There are also tips on painting and many other things here that are worth checking out.
All-in-all is was worth the $10 for me being at the beginner stages of 3D printing, but I felt like if you were going to charge to put together a bunch of free or already made tutorials, you should take the time to update them and keep them current.
