The concept involves creating digital models of organs using MRI and CT scans and then collecting patient-specific cells for use in the printing process. These cells are cultured to produce the necessary “bioink.” The collagen matrix is then 3D printed to act as a scaffold for living cells to grow. After organ implantation, the collagen matrix gradually dissolves and is replaced by living cells.
Although the technology has not yet reached the stage where fully functional 3D printed organs can be routinely transplanted, it is actively used for research and drug testing.
This research could potentially save the lives of approximately 900,000 people per year by allowing the creation of an infinite number of organs for transplantation, ultimately reducing costs compared to traditional organ transplants.
Commercial companies such as Organovo have made significant advances in bioprinting, providing models for studying diseases and investigating gene involvement.
As technology and commercial applications advance, 3D printing for organ replacements may become more affordable and practical in the future, but it is too early to tell when that will happen.
