Team : Sanna Siljander, Pasi Keinänen and Anna Räty (TUT), Atsushi Tanaka and Jani Lehmonen (VTT), and Anastasia Ivanova (Aalto University) BACKGROUND The research aim was to achieve optimum conductive properties to cellulose based non-woven, using minimum amount of […]
Team : Ville Klar, Pyry Kärki, Petri Kuosmanen (Aalto University) Hannes Orelma, Tiia-Maria Tenhunen (VTT) BACKGROUND A 3D-printer prototype was developed to explore various cellulosic materials in additive manufacturing. Various paste extruders were developed, tested and compared to commercially available paste […]
TEAM: Ville Klar, Pyry Kärki, Anastasia Ivanova (Aalto University), Hannes Orelma, Tiia-Maria Tenhunen, Jaakko Pere (VTT) BACKGROUND Different cellulose-based materials have been successfully 3D printed during the DWOC project. A 3D-printing test platform has been developed to systematically test and improve […]
TEAM: Tiina Härkäsalmi, Jukka Itälä (Aalto University) & Jani Lehmonen, Jukka Ketoja (VTT) BACKGROUND Foamed pulp is used for the production of sound absorbing and insulating panels. The material’s density, stiffness, permeability, heat insulation or sound absorption can be tailored. […]
TEAM: Pauliina Varis, Ilona Damski, Marjaana Tanttu, and Pirjo Kääriäinen, (Aalto University), Tiia-Maria Tenhunen, Hannes Orelma and Kari Kammiovirta (VTT) BACKGROUND We have previously shown the possibility to utilize several different cellulosic materials on fabrics by 3D printing. Now we are moving […]
TEAM: Vesa Kunnari (VTT), Heidi Turunen (Aalto University), Timo Kaljunen, Jaakko Pere, Ali Harlin, Ulla Salonen, Vuokko Liukkonen (VTT), Jyri Roppola (TUT, student), Kirsi Kale (Omnia, student) BACKGROUND Method to produce a novel laminated material structure combining nanocellulose and cellulose has been […]
TEAM: Yibo Ma, Marjaana Tanttu, Shirin Asaadi, Michael Hummel, Herbert Sixta (Aalto University) BACKGROUND Upcycling is becoming an increasingly hot topic in our society. It is part of the new bioeconomy concept which promotes the production of value added products with […]
TEAM: Jani Lehmonen, Jukka Ketoja, Atsushi Tanaka (VTT) Heidi Turunen, Anastasia Ivanova (Aalto University) BACKGROUND Board is produced from pulp by foam forming and pressing. Foam forming enables production of a vast variety of fibre-based materials. Material of these boards […]
TEAM: Ville Klar, Petri Kuosmanen (Aalto University) Hannes Orelma, Hille Rautkoski, Tiia-Maria Tenhunen (VTT) BACKGROUND Deep eutectic solvents can be used as a spinning medium for producing wood fibre yarn without dissolution. We constructed a modular prototype spinning line, where […]
Nanocellulose can be processed using molding technology to extremely light and strong tubular structures. With material thickness less than 1 mm, it is strong enough for numerous load bearing applications. Demo Products Nanocellulose bike Design and manufacturing: […]
