The world's first 3D printing flexible heart was born, and the 3D printing technology has not been mature so far, so the 3D printing heart can not be implanted into the human body, but it provides a new development direction for the artificial heart, maybe it can be realized in the future?
Swiss researchers have created the world's first flexible heart with a shape, size and function similar to a human heart by using 3D printing technology. Although the artificial heart is still in the stage of conceptual testing and can not be used for transplantation, it provides a new idea for related research.

According to the Xinhua News Agency on July 19, Nicholas & middot; Coles of the Federal University of technology in Zurich and others reported in the new issue of the American Journal of artificial organs that the artificial heart is made of soft silica gel material by 3D printing and lost wax casting technology. It weighs 390 grams and has a volume of 679 cubic centimeters.
The new artificial heart is a silica gel body with complex internal structure, including a right ventricle and a left ventricle, and an additional chamber to separate the two ventricles. The chamber functions like a muscle and pumps blood into and out of the heart. (this article is exclusively compiled by WYH, editor of sihai.com.

Although the commonly used artificial heart blood pump and other devices can pump blood, its mechanical components are easy to bring adverse effects to users. "So our goal is to develop an artificial heart about the same size as the patient's heart and try to mimic the shape and way the human heart works as much as possible," Coles said. '
However, the artificial heart is still in the testing stage. Due to the limited bearing capacity of the material, it can only run for about 3000 times, that is, it can work for 30 to 45 minutes. Coles admitted that the tensile strength and performance of the material still need to be greatly improved, and the current products can not be implanted into the human body, but can provide a new development direction for artificial heart.
