3D systems recently announced a clay printer, the "Cerajet", that's intended for producing ceramic objects (they'll need to be fired after being printed) http://www.3dsystems.com/press-relea...ttm-3d-printer. It appears to be based on the Z-corp printers, which have been adapted to ceramics by experimenters: http://www.youtube.com/watch?v=WmVLQHAH-V4 but it's not actually available for purchase yet - it will be soon, though, and for under $10k.
