Patent abstract

A material feed system for solid freeform fabrication. The build material is delivered in discrete or quantized amounts by a clamp feed system in a non-flowable state to the dispensing device and the material is then changed to a flowable state prior to being dispensed. The feed system can be used to build three-dimensional objects in color, if desired. The clamped feed system is integrated with a waste removal system.
