The heart-making process began with the biopsy of adipose tissue taken from the patient. The cellular material of the tissue was used as the "ink" of the print job. This allowed researchers to create complex tissue models including cardiac patches and eventually whole heart. It is important to note that the heart is not very large. It is only about the heart size of a rabbit. But the technology that made this possible can eventually create a human-sized organ. Hearts can only contract now, but researchers teach how to cultivate and actually trade 3D printed hearts. Once the process is complete, it will attempt to transplant it into an animal model.
Researchers have been working in 3D printing organizations for many years and have the ultimate goal of creating a functional institution for transplantation. Scientists at Tel Aviv University's heart project have theorized that organ printers can be used in hospitals within 10 years.
