Is it visible light, UV or infra-red??
Red is full of questions on this one. We used these in the past. The system I was familiar used the laser to cut/and fuse layers of paper together to form the 3D solid. Slow and only provides "approximate components due to the limitations of the paper."

The machine connects to a desktop computer running software that controls its operation. It then creates objects layer-by-layer by squeezing material from a mechanically-controlled syringe. A video shows a completed machine constructing a silicone bulb (16MB, wmv format).
Unlike commercial equipment, the Fab@Home machine is also designed to be used with more than one material. So far it has been tested with silicone, plaster, play-doh and even chocolate and icing. Different materials can also be used to make a single object – the control software prompts the user when to load new material into the machine.
