About a month and a half ago, I was fortunate enough to tour the local motors factory. The guys there mentioned that they could really use a 3D printer that could produce larger objects in plastic than their Makerbot is capable of. Check out the video below to see one in action!
My favorite thing about this 3D printer: It is a cross between rapid prototyping technology and a microfactory. The delay between imagining a new chair design and sitting on the real thing is incredibly, amazingly, wonderfully short if all you need to do is make a 3D CAD file, print it, and sit down.
Dirk Vander Kooij, the designer/programmer/creator of this amazing piece of work, calls the chair that he is printing the "endless chair" because it is made of a seemingly endless (400m) line of plastic. I'm not personally sold on the name, (400m = endless?? Really??) but last time I checked, by the time you are awesome enough to turn old factory equipment into a programmable 3D printer then use it to manufacture fully functional furniture of your own design, you don't need universally appealing product names to be a smashing success.
Way to go, Dirk!
