3D Bioplotter Research Papers

Eco-friendly materials are increasingly important for several applications due to growing environmental concerns, including in robotics and medicine. Within robotics, silicone-based soft grippers are recently developed owing to their high adaptability and versatility allowing to deal with various objects. However, the soft grippers are difficult to recycle and may cause increased environmental impact. Here biodegradable soft pneumatic actuators reinforced by cellulose nanofibrils (CNF) distributed in a matrix of gelatin are presented. The results show that adding CNF enables 3D printability and provides tunable mechanical properties for the actuators. The actuator performance, with a bending angle of 80° and a blocked…
