ZURICH, Switzerland — For the first time, scientists have created a robotic hand complete with bones, ligaments, and tendons using advanced 3D printing technology. In a significant leap for soft robotics, scientists harnessed a novel technology that integrates 3D printing with a laser scanner and a feedback loop.
A United States-based startup is now commercializing this technology, printing complex objects upon request. The breakthrough extends 3D printing capabilities beyond fast-curing plastics to include slow-curing plastics, which boast superior elasticity, durability, and robustness.
This advancement is credited to the collaborative efforts of researchers at ETH Zurich in Switzerland and the startup company, enabling the creation of intricate, long-lasting robots from various high-grade materials in a single process.
The technology also simplifies the blending of materials with different levels of softness and rigidity. It allows the construction of delicate structures and components with internal cavities according to specific requirements.
“Robots made of soft materials, such as the hand we developed, have advantages over conventional robots made of metal. Because they’re soft, there is less risk of injury when they work with humans, and they are better suited to handling fragile goods,” says Prof. Robert Katzschmann.
