Unfold has a summary page about unfold ceramic 3d printing.
Ceramic paste extrusion.
I look forward to seeing the pics of the ceramic pieces after firing.
Magnetic stirrers to develop a suitable paste for extrusion.
Paste eliminates extrusion defects resulting from dilatancy often found in water based systems.
In filters these channels are responsible for trapping harmful particulate matter before it reaches the air.
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.

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.
The mixture is then transformed into a paste like substance.
A simple and facile method was developed to fabricate functional bulk barium titanate batio 3 bt ceramics using the paste extrusion 3d printing technique the bt ceramic is a lead free ferroelectric material widely used for various applications in sensors energy storage and harvesting.
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.
