Check out this 3-D printer. The video demo shows this odd contraption as it prints leather shoes, screen doors, plastic jugs, aluminum cans, a complete sofa, tennis balls and leather belts. Even edible fruit and vegetables.
The inputs are a little peculiar though.
In the back of my mind, I am wondering if someone is pulling my leg, but I don’t think so. Some misinformed people may claim this is actually a shredder, but those people are wrong.

I don’t think it is commercially available.
Some rather more promising 3-D printers are discussed here, here, and here.
