Continuous Clay Printer Conceptual Design

Concept:

1. Clay powder and water is used to allow easy mixing
2. Excess water allows easy mixing in a columnar vessel just by using a mixing blade like in a blender
3. Allow time for clay to settle out
4. Once settled, air pressure can be applied to push the clay out, with excess water on top acting as the 'piston'
5. Clay is pushed out through an extruder
6. Print head has a valve that shuts clay flow on/off, but retraction is not easily done

Questions:

1. Is settling time acceptably short (such as one day)?
2. Is settling effective, or will the clay remain too wet?
3. Is "plaster table"-like dewatering required?
