Gosh, so many changes are coming our way... I can't wait! I find 3D printing so fascinating! The idea sounds like some sort of Sci-Fi movie that can't become a reality. It seems impossible in my mind, but yet here we are! The technology is going to become as popular as a microwave. Seriously, things are moving at a such rapid speed, I think all predictions will be blown away, because all of this might start moving even faster and faster.
