Understanding 3D Printing Volume 4 available now: http://www.amazon.com/Understanding-3D-Printing-Refining-ebook/dp/B00DX4GC9I
It should be pointed out that @Al_Williams is also the author of the book.
@ThantiK I assumed that was obvious
@Joe_Duong At the moment, yes. In order to give volume 1 away the other day you have to be exclusive with AMZ for 90 days. Strange.
Kindle is “cracked” so you can buy the kindle-edition and then on your desktop convert it to eg ePub.
And of course I bought the books
In addition, you can read Kindle on phones, tablets, and desktops too.
For the record you can now get all 4 volumes in one download (33% off getting them all separate) http://www.amazon.com/Understanding-Printing-Volumes-1-4-ebook/dp/B00DXHBD2G
