MIT has developed OpenFab, a programmable pipeline for synthesis of multi-material 3D printed objects that is inspired by RenderMan and modern GPU pipelines. The pipeline supports procedural evaluation of geometric detail and material composition, using shader-like fablets, allowing models to be specified easily and efficiently. They describe a streaming architecture for OpenFab; only a small fraction of the final volume is stored in memory and output is fed to the printer with little startup delay. They demonstrate it on a variety of multi-material objects.
A procedurally-defined foam material makes the bunny and bear squishy. Color and squishiness vary procedurally over the models.
Openfab was presented at Siggraph 2013
