	The testrun went well, a constant amount of material was extruded. It's important to note that the air pressure shouldn't be set to high as at some point the material will be pushed through the auger by the pressure alone. The next test should be made with a real stepper motor and the right nozzle.		The testrun went well, a constant amount of material was extruded.

	The auger housing is completely printable. How well it works with abrasive media is not yet clear and has to be tested. Alternatively it can be made from alloy or other metals. The auger housing takes a normal 5mm drill as auger. On top the drill is fitted into a 105 2RS bearing.		The auger housing is completely printable.

	The housing is designed with G1/4 threads for the nozzle and the material feed. G1/4 connectors to almost anything are widely available.

	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]).

	The Claystruder is a device that replaces the plastic extruder with an compressed air syringe extruder which is capable of extruding high viscosity materials like clay or cement. The design is based on the original Claystruder by the design studio [http://unfold.be/pages/projects unfold] from Belgium which in turn is based on the [http://wiki.makerbot.com/frostruder-mk2 Frostruder MK2]. Our design takes a 100cc [http://www.bbraun.de/cps/rde/xchg/bbraun-de/hs.xsl/products.html?id=00020741570002086064&prid=PRID00000404 Braun Omnifix] syringe which is in stock at local pharmacies for ca. 2.50€ per piece.
