Diferent Material Extrusion:

Wood Pulp

The first BioMaterial I tried to print was WoodPulp, in this system you can see the Thingiverse concepto validation of the extruder working with the tanks first version.

White Clay

The second material I tested was White Clay, eventhough this is not a BioPlastic, I worked with this material, cause it is easy to make and more accesible. Most of the test where made using this material, until I got a final version and went back to the BioPlastics.

Lignin

The last material I tested was Lignin. To print this I used the AirFlush system and the final Extruders Final Version.
