Cellulose nanofibrils have properties that can improve the characteristics of bio-based 3D-printing pastes. VTT Technical Research Centre of Finland is developing a 3D wound care product for monitoring wound condition in hospital care. However, the first commercial nanocellulose applications will be seen in indoor decoration elements, textiles, and the production of mock-ups.
3D printing has proven to be an efficient manufacturing method for complex, customized, and light structures. In addition to thermoplastics, 3D printing materials include metals, ceramics and foodstuffs. The range of biomaterials in 3D paste printing is still fairly limited, since pastes pose unique challenges: their structure must not collapse during printing and the objects manufactured must remain sufficiently strong, rigid or flexible after drying. In 3D biomaterial filaments, however, commercial products already exist … read more
