Solid freeform fabrication (SFF) techniques represent a class of manufacturing processes for creating 3D tissue scaffolds. One particular SFF method uses material deposition from a nozzle that undergoes piecewise linear motion. This work develops a process model for this manufacturing device using a swept volume representation of the capabilities of the tool. Specifically, a swept volume, including internal and external structures of scaffolds, describes the tool path information and defines the scaffold to be fabricated. This swept volume based model can be used to simulate the scaffold fabrication process, and to generate a virtual scaffold prototype.
