Swiss researchers  have come a step closer to building to a better artificial heart. It’s a squishy prototype that’s 3D-printed from silicone. This soft artificial heart also has a chamber that fills up and deflates, mimicking the muscle contractions of a human heart.

Traditional artificial hearts are made from plastic and metal, which the human body can reject. The 3D-printing method would also allow doctors to customize the size and fit of each soft artificial heart to the patient.

The heart is still a work in progress. It beats for about 30 minutes or about 3,000 beats before the silicone breaks down. The next step is for researchers to improve the material and design.
