Researchers have made a breakthrough in 3D printing by successfully creating a robotic hand with bones, ligaments, and tendons made of different polymers. This was made possible by a new technology that combines 3D printing with a laser scanner and a feedback mechanism. By using slow-curing polymers with enhanced elastic properties, the researchers were able to produce a more durable and robust robotic hand. This technology also allows for the combination of soft, elastic, and rigid materials and the creation of delicate structures and parts with cavities. The advancements in 3D printing open up new possibilities for soft robotics and the production of complex objects.
