Solidification of 3D printed nanofibril hydrogels into functional 3D cellulose structures
Artikel i vetenskaplig tidskrift, 2016

Cellulose nanofibrils isolated from trees have the potential to be used as raw material for future sustainable products within the areas of packaging, textiles, biomedical devices, and furniture. However, one unsolved problem has been to convert the nanofibril-hydrogel into a dry 3D structure. In this study, 3D printing is used to convert a cellulose nanofibril hydrogel into 3D structures with controlled architectures. Such structures collapse upon drying, but by using different drying processes the collapse can be controlled and the 3D structure can be preserved upon solidification. In addition, a conductive cellulose nanofibril ink is fabricated by adding carbon nanotubes. These findings enable the use of wood derived materials in 3D printing for fabrication of sustainable commodities such as packaging, textiles, biomedical devices, and furniture with conductive parts. Furthermore, with the introduction of biopolymers into 3D printing, the 3D printing technology itself can finally be regarded as sustainable.
