3D Printing always gets people excited whenever we mention it, and this excitement is all over. Consider the YouTube video of ten year old Schuyler St. Leger speaking at Ignite Phoenix, in which he describes with some passion his thoughts on 3D printing and the maker community. His hugely entertaining talk is definitely worth viewing.
Kerry Stevenson, aka "General Fabb" has written over 8,000 stories on 3D printing at Fabbaloo since he launched the venture in 2007, with an intention to promote and grow the incredible technology of 3D printing across the world. So far, it seems to be working!
