Scientists have developed a soft artificial heart made of silicone with 3D printing and a lost candle technique to help people with heart failure cling to life. Today, heart-pumping devices for blood pumping have disadvantages for the body. The size of the washing machine, which keeps patients connected to a hospital bed, requires the placement of mechanical implants that cause other complications, artificial hearts that will not affect the standard of living of the patients. Scientists have set out on this path and have developed a soft silicon heart, just like a real heart, with 3D printing technology. 3D printing and lost candle technique is used. ETH Silicone artificial heart, designed to mimic the natural heart of Zurich scientists, waiting for heart transplantation Was developed to help the patient. The artificial heart, which is the same size as a human heart, weighs 390 grams.
A special method called 3D printing and lost wax technique has been used to create the heart that is designed in rooms. Compressed air chambers provide fluid pumping as well as real heart. When tested, the researchers use a viscous liquid similar to human blood and detect that they work basically like a human heart. The most important problem in front of the artificial heart is; It can last up to 3000 shots, equivalent to about 30-45 minutes. Scientists say that the feasibility studies are an important step in the material and technique used in this work in ongoing artificial heart technology.
