Brinter is assisting the University of Gothenburg in the RESTORE project with the optimization of the nanocellulose/alginate-based bioink to improve its printability and cartilage tissue regeneration. For test purposes, simple test patterns, e.g., tubes, have been printed using different printing technologies, such as pneumatically controlled Pneuma Tool. These test patterns are used to evaluate the suitable material composition and CaCl2 pre-crosslinking conditions necessary to result in dimensionally accurate and stable printed structures. The development work continues as we speak with the addition of functional nanobiomaterials fabricated by other RESTORE consortium partners into the ink.
