On July 17, 2017 (June 24, 2017 in the lunar calendar), the world's first 3D printed soft artificial heart was born: it can only jump for 45 minutes. On July 17, 2017, according to foreign media reports, Swiss researchers have developed an artificial heart that is very close to a real organ "in shape and function. 3D printed soft artificial heart According to the researcher NicholasCohrs, it is made of silicone resin, weighs 390 grams, 80 grams more than a normal heart, and contains a" complex internal structure ". Mimicking a real human heart, this simulated heart contains the right and left ventricles and is shaped by 3D printing technology. 3D printed soft artificial heart These two chambers are not separated by a diaphragm, but are instead pressed out by another chamber through pressurized air. The chamber used to pump fluid simulates muscle contraction. "Our goal is to develop an artificial heart that is about the same size as a patient's heart, and that mimics a human heart as closely as possible in form and function," said Cohrs, a PhD student at the Swiss Federal Institute of Technology who led the team. The researchers found that while it functions similarly to the real thing, due to limitations in soft materials, its functionality is limited to 3,000 beats, or 45 minutes for the longest beating. While the developers did not intend for this model to become a temporary implant immediately, it has paved the way for thinking about artificial organs. " This is just a feasibility test. "Our goal is not to prepare implanted hearts, but to provide a new direction for the development of artificial hearts," says Cohrs. However, the hope is that the development will change the function of current blood pumps, which researchers say is prone to complications. About 26 million people worldwide suffer from heart failure, and the new technology could close the gap between demand and providers.
