3D Printer technology prints ears, first implanted

It has been more than 30 years since the birth of the world’s first commercial 3D Printer. With the advancement of technology, 3D Printer is more and more closely related to our lives. In recent years, this advanced technology has gradually penetrated into the medical field. At present, 3D Printer has covered many scenarios such as surgical model preview, orthopedic implants, surgical navigation, medical rehabilitation equipment, etc., and has also developed in the field of organ printing.

Previously, researchers at Carnegie Mellon University used their free-form reversible embedding of suspended hydrogels (FRESH) technology to create the first full-scale 3D bioprinted digital model of a human heart. This novel additive manufacturing method allows not only the creation of complex organ features but also organ functional properties. Undoubtedly, this has greatly inspired the exploration of 3D Printer organs.

3DBio Therapeutics, a regenerative medicine implant technology company, announced today that it has successfully transplanted a 3D Printer ear made from human cells into a woman born with a rare ear deformity. This transplant marks a major step forward in tissue engineering with 3D Printer.

Microtia is a type of ear deformity that affects about 1,500 babies in the United States each year with microtia, a condition in which one or both ears are underdeveloped or completely missing. Typically, patients with microtia have ears made of rib grafts or synthetic materials. But in this study, the researchers took living tissue from the patient’s ear, extracted cartilage cells, and then grew these cells and 3D Printer into the shape of the patient’s ear.

Unlike 3D technology Printer internal organs, printing ears is significantly simpler, and compared with livers, ears are not necessary to maintain human life, so the success rate in human experiments is higher. Also, because the ear is made from the patient’s own cells, there is less chance of rejection.

Although 3D Printer organ technology can not only solve the problem of organ supply, but also reduce the rejection reaction, but the current high cost of 3D Printer equipment and medical products, not only ordinary patients can not afford, even most medical institutions can not afford. In addition, for some small and difficult operations with small tissue structure, how to achieve the precision and standardization of the operation through 3D Printer is also a problem that needs to be broken through.

In any case, the application of 3D Printer organ technology in the medical field has become a trend. Once the problems of materials, cost, and accuracy are overcome, it is believed that the 3D Printer medical market will achieve breakthrough progress.
