Release date: 2017-07-17 The Antarctic Bear is looking forward to the fact that one day 3D printing technology can create an alternative artificial heart, helping patients waiting for heart transplants to relieve their pain. Obviously this is a long and challenging job, and scientists are working hard on it. On July 14, 2017, the Antarctic Bear learned that researchers at the Functional Materials Laboratory at the Swiss Federal Institute of Technology in Zurich have used 3D printing to create a silicone heart that beats almost like a real heart. This artificial heart lasted about 3,000 beats, about 30 to 45 minutes. No one really knows when a portable 3D printed heart can become a reality, but it doesn't stop researchers from trying to use 3D printing to make an advanced copy of the heart of one of our most important organs. ETH Zurich scientists recently used 3D printing to create a functional silicone heart that beats almost like a real heart. Exciting research projects have shown that soft artificial materials can be used to create functional artificial hearts or other cardiovascular devices. Nicholas Cohrs, Ph.D. student of the ETH Zurich Research Group, commented: "Our goal is to develop an artificial heart of roughly the same size as the patient itself, and to mimic the human heart as much as possible in form and function." Artificial hearts are often used as a "hemostasis" solution when patients are waiting for a heart transplant. Some 26 million people around the world suffer from heart failure, but there are not enough donors. This 3D printed heart has a left ventricle and a right ventricle that are separated by an additional chamber rather than a septum. This special chamber inflates and deflates with pressurized air and draws fluid from the blood chamber. Therefore, it can replace the muscle contraction of the human heart. A silicone heart made using 3D printing and lost wax casting technology weighs 390 grams and has a volume of 679 cubic centimeters. Cohrs said: "It is a silica gel structure with a complex internal structure. There are many reasons why this silicone heart cannot be implanted in the human body. Currently, it can only last about 3,000 beats, about 30 to 45 minutes. “This is just a feasibility test,†Cohrs said. "Our goal is not to prepare for the implantation of the heart, but to consider the new direction of artificial heart development." To test their silicone heart, the researchers used the most advanced test environment to simulate the human cardiovascular system. Use a fluid of comparable viscosity to human blood. Anastasios Petrou, a PhD student at the Zurich Product Development Organization, commented: "At present, our system is probably one of the best systems in the world. Artificial heart research has been published in the Journal of Artificial Organs for the development of safer and more biocompatible. Artificial heart.
