(at around 12 mins) The computer-controlled "rapid prototyper" portrayed in this movie is real technology, known as a 3-D printer, able to mechanically sculpt parts and objects in three dimensions using computerized drawings and scanned information. The machine in the movie uses Laminated Object Manufacturing (LOM). Using one thin layer of bond paper and resin at a time, it carves away the unwanted material as each layer is added, until all the cross-sections have been built up into a solid replica of the original. The carving action of each layer creates a great deal of shavings and dust during the process, which you can see when Billy lifts the lid up to remove the finished model.
