The Science Siblings are celebrating Heart Month this February with some facts and a DIY model.

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.

An engineer has created a 3D model of the human heart, inspired by his daughter’s heart condition, with the goal of creating a library of virtual hearts for researchers to use whenever they want.

How to Make Human Hearts, Lungs, and Guts Using Only Paper Using white card stock, scissors and some glue, Horst Kiechle created an anatomically-correct model of the human torso with removable organs.

Science Astounding 3D-printed human heart model cuts and sutures like the real thing The full-size, life-like model could give surgeons a chance to practice their life-saving skills.

A minuscule model of a human heart, the size of a grain of rice, has been created in Israel. With the potential to put an end to the often criticized animal testing by pharmaceutical companies.

The resulting model comprises multiple chambers, pacemaker clusters, epicardial membrane and endocardial lining, all meticulously designed to mimic the structure and functions of the human heart.
