The world's first 3D-printed heart model

Tel Aviv University scientists said that they have printed the world's first 3D heart, using cells and biological material from a human patient.

It took about three hours to print the whole heart. The lab-printed heart is approximately 100 times smaller than a human heart.

Similar to a rabbit heart in size, the model demonstrates the potential of 3D-printing technology for producing personalized tissues and organs.

"This is the first time that an entire heart was successfully engineered and printed with cells, blood vessels, ventricles, and chambers," said Tal Dvir, a Tel Aviv University professor.
