Soft Tooling for Low Production Manufacturing of Large Structures

A new technique for building large prototypes from layered substrate relies on a higher order construction algorithm to produce accurate prototypes from thick layers. The process is capable ofproducing a 4' by 8' by 20' object in less than two days. Using this technique to produce molds instead ofparts allows construction oflarge castings and composite structures. Example parts include composite airfoils, a 19 foot canoe, and a custom fairing for a racing car.
