A group of scientists produced hands with extremely realistic features using a special 3D printing technology. This hand hosts structures such as bones and tendons.
3D printing technologies have been a subject of medicine for a while. In the past, 3D printers sometimes with corneasometimes vein produced. The latest news reveals that the methods used continue to improve. Scientists are now using 3D printers, very similar to the real thing They managed to produce a hand.
Scientists who continue their studies at ETH Zürich University, different polymers They managed to produce a hand using the combination. There is nothing very exciting so far. But what happens next is a bit interesting. The hand printed with a 3D printer has bones, connective tissue and tissues just like a real hand. to tendons is hosting.
It can also return to its original shape after being bent.
The robotic hand produced with a 3D printer has some interesting features. For example, this hand is at every point, just like in reality. not the same hardness. Moreover, the polymers used during production can regain their original shape after being bent. Thomas Buchner, the leading name in the research, said that this could be done with traditional 3D printing technologies. that it wouldn’t be possible he stated. There are some justified reasons why the scientist speaks so clearly.

Researchers used a special technique to produce this hand. from laser technology they benefited. This technology made the necessary checks on each layer of the print and determined where harder and more elastic polymers would be used. Laser technology, which also enables recalibration for each stage, near perfect Assisted in producing prints.
Although the most significant pressure the team performs is a hand different for products Studies were also carried out. Thus, it became clear that the developed technique could actually be used in many areas. The scientists, who are very satisfied with their techniques, say that they will continue to work and improve the print quality even further. they will heal They explained.
