Add 15 ounces of water to the bag, close the bag and make it airtight. bag of prepared clay, cut the clay into 4 pieces and put a microfiber towel in between the 4 pieces. It is necessary to have an adaptor for the nozzle of the pug mill to attach the polycarbonate tube for loading.

This happens because the auger has no traction against the side of the pug mill as the clay mixture becomes too loose. It also depends on the pug mill and its ability to forcefully push the clay.

If too much water is added to the clay the pug mill can actually not function sufficiently enough to load the tubes. This can be accomplished by running the clay through the pug mill and adding a small quantity of water. The consistency of the clay should be similar to standard throwing clay, but wetter. Although a single auger is adequate, the consistency of the clay is more critical when it comes to loading the tubes. For best results, a de-airing pug mill and a double auger will give you better performance than a single auger. The easiest way to load extruder tubes is with a pugill. We have yet to make up our own clay preparation and this is another way to go. There's so much to say and so much experimenting to be done in our 3D ceramic studio. This also depends on the environment's temperature and humidity. Especially on larger vessels at the overlap point after a period of time, the moisture doesn't seem to be there. The interlayer adhesion seems to be a problem as the moisture dissipates too quickly on a large print. Porcelain - Axner Mary's Porcelain Clay is the only porcelain that we have experimented with. The interlayer adhesion is a little bit less than the stoneware also but this doesn't seem to be a problem as long as you do not let the moisture come out of the clay too fast after printing. We do add some water to the stoneware which seems to help with interlayer adhesion and ease of extrusion.Įarthenware - Vince's Low White Clay earthenware performs well also although it does not extrude as easily as the stoneware. Stoneware - Maccabees cone 5 stoneware has the best interlayer adhesion and is quite easily extruded in our extruders. You can get it in prepared bags and use our preparation method. Some Clay Recommendations and ObservationsĬlay - Laguna B-Mix 5 WC401. Then the tubes can be loaded directly from the pug mill. Use a pug mill and add small amounts of water while cycling the clay through the pug mill several times to get the right consistency. Manual wedging with adding extra water until the consistency is right.ģ. The moisture from the cloth will penetrate into the clay in about a day or so.Ģ. Cut clay into smaller sections, put in microfiber towel or felt in the plastic bag, and 10-15 oz.
