3D Bioprinting as a more advanced way of human structure production

Bioprinting is the more advanced way of 3D printing process. Instead of using materials such as ceramics, plastics or metals, we are utilizing biomaterial, which usually has living cells in it. Due to that the part of the human body such as skin tissues or organs can be printed out. Such a technology advancement may be a solution in replacing the failing kidney or other defective organs, which is one of the most desirable medical applications of the 3D printing industry.

The main challenge is to be able to print out fully functional, long-lasting organs. For the present moment, it is still not possible to produce 3D printed organs that don’t have to get replaced within a few days or months. Also, the process also includes connecting the 3D printed organ into the living organism and cells. Before that, a lot of safety tests and requirements need to be passed and ensured.

Bioprinting in terms of 3D printing technology

Beginning with CT and MRI scans and taking the cells sample from the patient is the base for printing out the living organ. Then, the bio-ink needs to be received and provided to the printer. 

Modeling or prototyping is the next step. Conducting them first is the way to print out the organic objects. This can be done thanks to the software. In order to be able to print out the living organ, we need to get the digital model first. 

The organic project will be then printed on the very thin kind of layers. However, to successfully begin bioprinting, a mix of different techniques is predicted to be used. They are already being tested and developed with the aim to improve bioprinting. Implementing various methods and fields as well as the possibilities of the technologies, bioprinting can boost and get accelerated.

The bioprinting limitations to overcome 

There is still a lot to be settled before bioprinting will turn out completely successful. As the human body has a very complex structure, it’s not easy to fit in the 3D printed object without any obstacles. 

However, one way or another, investing in research, constant testing, and trials are the key for bioprinting to become a new, common way of replacing the failing organs. It would also be a great way to reconstruct the damaged human body parts after the accidents. Replicating the original ones, the organic implants could be possibly printed easily and fast

Taking into account all of the above features of bioprinting, it could definitely be the most advanced application in medicine. There are still a lot of limitations such as human body complexity, inserting the living cells into the printing technologies or safety and efficiency assurance, however instant development of bioprinting can make the process posible and commonly used in the near future.
