Introduction3D bio-printing is the process of creating cell patterns in a confined space using 3D printing technologies, where cell function and viability are preserved within the printed construct.

Generally, 3D bio-printing utilizes the layer-by-layer method to create tissue-like structures that are later used in medical and tissue engineering fields.

History & Recent situations The first patent related to this technology was filed in the United States in 2003 and granted in 2006.2006- Worlds first artificial bladder was built in a laboratory by 3D printing and transplantation done on 7 patients2009- Artificial liver was made by 3d printing.2011- Worlds first artificial trachea built by Bio-printing.2011- In situ skin Bio-printing for burn wound was done.2015- Partnership between Organovo and LOreal for Commercial production of artificial skin using bio-printing technology.

3D Bio-Printer

Process3D bio-printing generally follows three steps, pre-bioprinting,bio-printing,and post bioprinting.

Pre-bioprinting: Pre-bioprinting is the process of creating a model that the printer will later create and choosing the materials that will be used. One of the first steps is to obtain a biopsy of the organ.Bioprinting: In the second step, the liquid mixture of cells and nutrients are placed in a printer cartridge and structured using the patients' medical scans.

ContdPost-bioprinting: The post-bioprinting process is necessary to create a stable structure from the biological material. If this process is not well-maintained, the mechanical integrity and function of the 3D printed object is at risk.

Printing Methods

Applications

Organovo, an "early-stage regenerative medicine company", was the first company to commercialize 3D bio-printing technology. The company utilizes its NovoGen MMX Bioprinter for 3D bioprinting. The printer is optimized to be able to print skin tissue, heart tissue, and blood vessels among other basic tissues that could be suitable for surgical therapy and transplantation. Bio-printing technology will eventually be used to create fully functional human organs for transplants and drug research, which will allow for more effective organ transplants and safer more effective drugs.
