3D-Printing (3DP) of cellulose powder
This project aims to 3D print cellulose. The printed parts consist only of cellulose powder mixed with cellulose ethers as binding agents. Similarly to binder jetting, successive layers of this mixture are spread out. Using an industrial inkjet print head from Fujifilm-Dimatix, isopropanol is selectively deposited on each of the powder layers. Isopropanol dissolve the binder and stick the cellulose particles together. The produced parts are fragile and require a post-treatment. A dedicated printer was devoloped and built for this project. Ongoing research is done on optimizing of the layer formation and drying to increase mechanical properties.
