looks interesting. Though sounds like it gives unrealistic expectations of 3d printers.

Love some of the reviews by (I assume) relatives ;-)
eff Ito is the reason why 3D Printing is growing so fast, from his first best 3D Printing seller that Amazon took on and advertised as the main book for 3D Printing, Jeff is now empowering the youngest minds to see the wave of the 3D Printing Revolution.

Your website is pretty good. Though having a forum that can't be accessed by non-members, probably not that great an idea.

Good luck with the book :-)
