printer. okay? and instead of the ink that the printer uses, i don't even know how to use it. instead of ink that the printer squirts out, this thing that we're going to tell you about actually squirts out plastic and builds plastic components that you can make something out of. let me introduce our guest christina, tell me a little bit about our guest. there he is. there he is. he's right there. he's the founder of maker-bot and he's got one with him. hard to see there. is that something that you can pick up or is that all we are going to see of it? >> this is a maker bot 3-d printer and i just finished making a bunny here in the cnn offices. you can use it to printout all sorts of things from gears to alien heads to dna structures. anything you want. i have a little ring here.
