Unlike humans and animals, robots do not have real bones or the flexible tissues that connect them; they have artificial links and joints made of materials like carbon fiber and metal tubes.

A team of researchers from the Swiss Federal Institute of Technology (ETH) Zurich and US-based startup Inkbit have figured out a way to 3D print the world’s first robotic hand with an internal structure composed of human-like bones, ligaments, and tendons.

“These have very good elastic properties and return to their original state much faster after bending than polyacrylates,” said Katzschmann, one of the authors on a new paper that describes the new method.

“This visual inspection makes the print process fully contactless, allowing for a wider range of possible polymers to be deposited.

We, for example, printed with thiol-based polymers because it enabled us to create UV-light and humidity-resistant structures,” Katzschmann told Ars Technica.

The high resolution, suitable material properties, and their long lifetime make prints from the VCJ system very useful for both research and commercial applications,” Katzschmann told Ars Technica.
