3-D printing is truly dynamic

There is no more exciting virtual/physical invention today, I believe,than 3-D printing. If, like myself you have followed this phenomenon from busts, to bikes to now human organs, you know how unexpected this evolution has been. Imagine a world where organs can be cell-jet printed, some day. Just the way pictures are ink-jet printed today. That's an amazing world. People would no longer have to wait long for replacements of kidneys or hearts or even lungs, when their own were diseased. As long as a software program was available to personalize the manufacturing of the organ the receiver would be in business. Now, in the entertainment world, 3-D movies are all the rage. Seeing a movie in 3-D is to view a sunset as compelling as the real thing. Such movies may in reality mean that 3-D is among us, but in effect the experience makes it harder for us to grasp 3-D printing and all of its huge potential. You can watch on Youtube now a bicycle being manufactured by 3-D printing: http://www.youtube.com/watch?v=hmxjLpu2BvY Or see two companies talk about the benefits of their printers: http://www.youtube.com/watch?v=S5POu62l_Wo
