Version two of the claystruder changes the design to a stepper motor driven auger extruder. Auger based extruders work by forcing material into a chamber with air pressure in which an auger rotates and transports the material through a nozzle. The variable motor speed allows for a more dynamic extrusion. Attempts to create auger based extruders are made by a number of different people (e.g. [http://reprap.org/wiki/Ceramic_Extrusion]). | Version two of the claystruder changes the design to a stepper motor driven auger extruder.

Our design utilizes printable parts in combination with a normal drill as auger and an additional bearing. All parts can be easily sourced and are quite cheap. | Our design utilizes printable parts in combination with a normal drill as auger and an additional bearing.
