Abstract

This project aims to 3D print wood by products. The printed parts are only made of cellulosic derivatives. The proposed process is powder based. Parts are made of semi-crystalline cellulose mixed with ethylcellulose (50/50). 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 ethyl cellulose, binding the cellulose particles together. The produced parts are brittle and require a post-treatment. A dedicated printer was built for this project. Ongoing research is done on optimizing of the layer formation and drying to increase mechanical properties.
