Make You Own Ceramic 3D Printer - Printheads/paste extruders

As a great believer in keeping things simple this shows the range of pressurised extrusion print heads or paste extruders that I use with the Delta 3D printer. For more information on Ceramic 3D Printing there is a Community on Wikifactory - see wikifactory.com/+Ceramic3DPri... .

That is so Macgyver! This is the person you want around if the S.S. Minnow is broken down on an island.
And no i wasn't referring to Australia.

Hi Jonathan excuse me I kind of want to make my self one of this ceramics printer I allready make my own 3d printers but since i have an small place I wonder if it is too loud the compresor to run the extrusor or an small one of 8bar 6Lt tank is enought for a few prints like empty cilinder 30cm Diameter and 40 cm tall?
thanks for all the information

Hi Matias, a cylinder of 30 x40 cm will take a lot of clay so you need a clay container big enough or be prepared to pause and change your clay container a number of times. As long as you have no air leaks with the compressed air, you only use up as much air as the amount/volume of clay that is being extruded. I have a small compressor with 8 L tank and 8 Bar cut off. I would expect it to only have to recharge once if I was to print something 30 x 40 cm. There are lots of variables like how thick the wall is, what size the layer height but as I say without air leaks and after initially coming on to get up to pressure the compressor should only switch on once more in a print of that scale. A 6 Lt tank is ok but will have to recharge a little earlier than a 8 Lt tank.

I wonder how hard it would be to make an auger extruder.

how did you build the syringe

[@micahturner1441]

You could use a pump system (something like www.thingiverse.com/thing:317726) That would give you the oppertunity to add more mix if needed during printing. Great job Jonathan!

Have you tried using a deflocculant for the clay like Darvan 7, Darvan 811 (Alkaline polyacrylates), or Sodium Citrate, used for casting slips. The clay becomes liquid or more plastic with greater adhesion with a lower water content.

It might eliminate some of the work in filling the clay syringe, and give the syringes much longer shelf life after being filled.
