In a groundbreaking development, scientists at ETH Zurich have achieved a significant milestone in 3D printing technology by successfully creating a robotic hand complete with bones, ligaments, and tendons. This remarkable achievement opens up new possibilities in the field of prosthetics and could revolutionize the lives of individuals in need of limb replacements.

By utilizing the latest advancements in 3D printing, the research team at ETH Zurich has overcome previous limitations in the technology. Traditionally, 3D printers were restricted to using fast-curing plastics, but the team has now made slow-curing polymers suitable for the printing process. This breakthrough enables the creation of complex structures, including delicate parts and cavities, with enhanced elasticity and durability.

The incorporation of bones, ligaments, and tendons into the robotic hand brings it closer to replicating the functionality and movement of a human hand. The different polymers used can be fine-tuned to mimic the elasticity or rigidity found in natural hands, providing a major advancement over existing 3D-printed prosthetics.

One of the key advantages of soft robotic materials, such as this innovative hand, is their reduced risk of injury when interacting with humans. Additionally, their flexibility makes them well-suited for handling fragile objects. These characteristics make the robotic hand an ideal solution for both medical and industrial applications.

This groundbreaking achievement has been published in the journal Nature, showcasing the potential of 3D printing in the field of prosthetics. With further advancements and refinements, this technology has the potential to transform the lives of individuals with limb loss, providing them with highly functional and personalized prosthetic solutions.
