Israeli scientists use 3D printing to create world's first model of human heart

JERUSALEM - Tel Aviv University scientists said on Monday that they had printed the first 3D heart, by using a patient's cells and scans.

The heart, which was produced in a lab, completely matches the biological characteristics of a patient's heart. It took about three hours to print the whole heart.

Making a human heart model is a major medical breakthrough. However, the printed heart is approximately 100 times smaller than a real human heart.
