3D-printed silicone heart made that beats like human heart
Switzerland-based researchers have 3D printed a silicone heart that beats almost like a human heart. The soft artificial heart has a right ventricle, a left ventricle and a chamber which is inflated and deflated by pressurised air, similar to human heart's muscle contraction for pumping blood. The material, however, lasts for only 3,000 beats, a lifetime of 45 minutes.
