Referring to the application of 3D printing technology in the medical field, the first thing people think of is to help people with disabilities print prosthetics. Yes, the pioneering development of 3D printing technology in the medical field starts with printing prosthetics.
Today, 3D printing technology can not only provide solutions to simulate the surgical process for the modern medical field, but also rely on the rapid development of printing materials. In addition to printing bones and prosthetics with high similarity to the human body, 3D printing technology can also print all kinds of soft tissues, muscles and other products that can be applied to the human body.
Researchers have developed a 3D printing synthetic soft muscle with “internal expansion ability”.
Incredibly, this 3D printed muscle can lift objects that weigh 1000 times its own weight, three times stronger than human muscles. It paves the way for the development of all soft robot.
It is reported that this new 3D printing synthetic muscle reproduces the behavior of muscle to a higher extent. To some extent, they themselves are a kind of soft robot.
Compared with other robots, such as pneumatic robots, soft robots have obvious advantages. They can grasp, manipulate and other natural movements, and often occupy less physical space than hard robots.
Due to the distribution of silicone rubber matrix with ethanol in the form of microbubbles in the whole muscle, the new 3D printed muscle has a lower density, and its strain density is 16 times that of organic muscle. This solution is cheap, environmentally friendly and easy to manufacture, providing flexibility and extreme volume change properties.
This means that scientists can now produce key components of humanoid robots, which will be far more powerful than humans. These 3D printing muscles are powered by an 8V low-power power supply through an embedded thin resistance wire. Tests show that when heated to 80 °C, they can expand by 900%. This expansion and contraction ability means that they can perform a variety of mobile tasks.
