The paste composed of ceramic polymer and solvent has a high yield stress but is able to weld to the previous layer before solidifying by solvent evaporation.
Ceramic paste extrusion.
Ceramic powder based on wet paste were extruded to give.
As another area of artistic experimentation particularly with the ceramic paste it would be interesting to try some post extrusion carving scraping gouging of the material once it had slightly hardened probably with a second head.
The mixture is then transformed into a paste like substance.
I look forward to seeing the pics of the ceramic pieces after firing.
Magnetic stirrers to develop a suitable paste for extrusion.
Unfold keeps a blog about progress on ceramic 3d printing and other topics at unfold fab.
The substance is then fed into a screw extruder and through a honeycomb die which creates thousands of tiny parallel channels.
Unfold has a summary page about unfold ceramic 3d printing.
In filters these channels are responsible for trapping harmful particulate matter before it reaches the air.
The method of state change used here results from a decrease of solvent content 10.
