Hands-on 3D printing (in clay)

Icebergs - digital pots by Jonathan Keep (www.keep-art.co.uk)

I've discovered another hands-on way of practising digital printing, this time using a paste of extruded porcelain driven by compressed air. You mix the clay and fill the cartridges yourself, and spoon powdered clay around the form to support it as it's built. (An alternative is to dry it with a hairdryer to harden the structure as it forms.)

It's demonstrated here by ceramicist Jonathan Keep.

The only problem from the point of view of my project is that the process is restricted to creating cylinders. The cylinder shape can be deformed in any way, but you need to design for a continuous extrusion of wet clay.
