A very recent study Research & Market 3D printing market will double by 2025, to reach $ 7 billion. This isn’t the most optimistic forecast but it is in line with other studies, but what may surprise most in this study, is that analysts estimate that 7 billion, 3 will be generated by what is called the bioprinting. In a few years, the impression of living tissue will pass purely experimental use for wide dissemination. Replace a body failed by his alter-ego healthy, printed in 3D has already nothing of science fiction. By 2025, it will be (almost) commonplace.
The medical sector already fond of 3D printing
3D printing was already a place of importance in the health sector. It is more particularly the case in the production of dentures and more for the realization of prostheses of any kind. Now, it is living tissue that interested researchers.
The example of TeVido BioDevices is edifying. The texan has developed a technique to help surgical patients of breast cancer. TeVido produces fabrics in order to achieve the breast construction tissues generated from cells from the patient and then 3D printed. To achieve TeVido BioDevices uses a classic office printer, a good old printer inkjet HP bidouillée and which allows to produce custom-made implants and which are not rejected by the patient, because made with its own cells.
The bio-printing arouses the enthusiasm of researchers
There are many examples such as TeVido. Both startups, public research centres, private institutes, they are indeed likely to develop techniques of bio-printing or bioprinting to do many parts of the human body: Organovo, allied with Janssen R & D (Johnson & Johnson group) are working on the 3D print of liver, Harvard Wyss Institute prints blood vesselsthe Cornell researchers, one ear, others working on the skin, cartilage, bone, bladder, kidneys, etc. The sector knows a genuine excitement and techniques become more accessible. Thus, an artist is allowed to print the ear of Vincent Van Gogh from the DNA of one of his descendants.
Multiple 3D printing technologies are available today to print living tissue: bio acoustic printing, inkjet, laser, by valve. Earlier this year researchers from Carnegie Mellon and Brigham & Women’s Hospital have developed the microrobot capable of generating a living tissue, in 3 dimensions.
No heart printed in 3D before 10 years
If certain techniques seem to be very advanced, researchers at Harvard have thus managed to print fabrics including their own network of blood vessels, all is not yet feasible, including perhaps the most symbolic body of the organ transplant: the heart. Institute cardiovascular innovation at the University of Louisville is working since the 1990s on the 3D print of the heart. Its researchers have already achieved results, but Stuart Williams, researcher of the Institute, finds that need another 10 years of work before you expect to print a human heart. Therefore, many years before the concept of man in kit is a reality.
