3D printing is the ability to take any object and recreating it with a printer. Now of course I do not mean on paper, but a plastic model version of the object. As this technology gets better, this will change manufacturing. 3D printing is absolutely amazing. Imagine being able to take an idea that you have and created it with a printer. I can think of a so many uses for this technology.
