Artificial 3D printed hearts work almost like human hearts

Applying biological mechanisms to prosthetic science, scientists created artificial hearts with the first 3D printing method, completely soft with silicone ventricles to help the blood pumping mechanism work well. like a real heart.

Between the ventricles of this artificial heart is not a real heart-like wall but a heaving chamber to pump. This is not a true heart but it is a very close step to the human heart.

With 3D printing, scientists have created a rather complex internal structure of the heart while still using soft and flexible materials.

The whole artificial heart is a single part (an "independent block"), so we don't need to worry about whether the various mechanisms within the body are compatible - except The port where the blood will go in and out. In tests, the 3D artificial heart works quite well with the ability to push blood-like fluid with human pressure.

But the materials that make up this heart can't work after a few thousand beats, meaning they work only for about half an hour, depending on your heart rate.

Currently, this artificial heart has not been implanted on human body but has only been applied in theory.

In the future, scientists want to continue studying to build a heart with a structure that can work much longer.
