This is an unnarrated process video showing how several top layers can be printed in clay over an infill pattern structure. In this case the nozzle diameter is 1mm and the layer heights are 0.5mm. The material is a white earthenware clay. I designed and built this custom printer. It uses a mechanical clay feed system and a motorized auger in the print tip, which is a cake frosting nozzle. A Duet 3D control board is the "brain" of the system. All motors are NEMA 23 and the linear motion system is leadscrew driven wheeled carriages on extruded aluminum rails.

I love to hear feedback, good or bad, and suggestions for videos about clay/ceramic 3D printing.
