based in Zurich at ETH public university researchers, Inkbit He achieved the impossible with a US-based startup called. First time with bones, ligaments and tendons they printed a completed robot hand; This represents a major advance in 3D printing technology. It is worth noting that the various parts of the hand are pressed simultaneously and are not put together afterwards.
Robot hand printed from 3D printer in one go
The various parts of the robotic hand were each made from different polymers of varying softness and hardness, using a new laser scanning technique that allows 3D printers to create “special plastics with elastic qualities” in one go. This obviously opens up new possibilities in the rapidly developing field of prosthetics, but also in any field that requires the production of soft robotic structures.
Essentially, researchers at Inkbit have developed a method to 3D print slow-curing plastics. However, technology previously produced fast-hardening plastics. This hybrid printing method offers all kinds of advantages compared to standard fast-curing projects, such as greater durability and improved elastic properties.
Technology also allows us to more accurately mimic nature, as seen in the robotic hand mentioned above. Robert Katzschmann, professor of robotics at ETH Zurich, talked about the study as follows: “The robots we have developed made of soft materials, such as the hand, have advantages over traditional robots made of metal.”
Because they are technically soft, there is less risk of injury when working with people and they are better suited for handling fragile goods.

Always young and well-groomed. Researchers are trying to find the age of Mars thanks to the Martian rocks that bombarded our planet.
MIT affiliated startup Inkbit, helped develop this technology and is already thinking about how to make money from it. The company will soon begin selling these newly produced printers to manufacturers. It will also sell complex 3D printed objects using the technology to smaller organizations.
