The CandyFab 6000 is an updated version of the larger 4000 model and can make 3D objects out of sugar. It uses Arduino boards to control the fabricating arms and fits on a desktop.
You will eventually be able to buy a kit to make one of these yourself. We would not recommend using the objects produced by this device in industrial situations. For example, do not make a sugar caribinier. It will only end in sadness.
